If you're thinking of buying a hearse, it means either you're passionate about woodworking and want to take it to the next level, or your old one is outdated, or where you work, on the construction site, in a joinery workshop, in a factory, additional needs have arisen that need to be addressed.
A hearse is necessary for those who need wooden boards with perfectly flat surfaces. Purchased timber does not always have clean, smooth surfaces. It has rough faces lacking flatness and different thicknesses that need to be adjusted in order to be used in furniture production. Therefore you will need to have the surface straightened and the thickness reduced accordingly in your factory or workshop. That's why I thought I'd try to answer 5 questions you should think about before buying a hearse.
1/What is a hedgerow?
Abric comes from the German abricht (rindea). The machine is also called planer. As the name suggests, the hearse is a kind of "automated heald" with high productivity and precision. Of course I'm pushing things a bit. It's a woodworking machine that efficiently straightens one side of a wooden panelalong its entire length. In addition, the edges can also be straightened, at 90° or at another angle, using an angle-adjustable parallel. Why do I say it's a kind of automated headline? Because you can be a very good carpenter without a heald. But these machines save time, they are "time savers" as English speakers say. Obviously you can use a rhindea if you're good and have all the time in the world. But even so, it's very hard to make a flat surface without the help of a jack. To draw a parallel with the "slow food", here would be a kind of "slow work". For the others, there is a hearse that solves the problem in minutes.
2/How does it work?
As I said, the heather is responsible for obtaining a perfectly flat and uniform face of a wooden panel. But what do we do when we need consistent thickness and flatness on both sides? Do we turn the wooden board over and machine it on the other side until we get a completely flat board of constant thickness?
No, because the heather only points one way, not the other. In this situation, a machine is used that performs the ginning operation. It's called thickness machine or thickness. It will machine the opposite side to make it flat and parallel to the other side already straightened. The differences between jointer and planer are also shown by Bruce Kieffer in this post.
There are also combined machines, which do both the shredding and the roughing operations. This type of machine is called thickness planing machine or abricht grosimeand with it you can do both. It works both as a heater and as a thicknessing machine. By successively straightening each side, using one machine, a panel of constant thickness with flat and parallel surfaces will result.
3/Is a simple hedgerow enough for what I have to do?
Why is there still a simple abric and not just a thick abric, because it does both operations anyway, planing and roughing? Because, depending on the specifics of the business, these operations are done differently and require different types of machinery. That's why there are so many different types of barbecues, from the very small and mobile ones used on building sites or in workshops like DIY, to complex ones for industrial exploitation.
So, depending on the specifics of your projects, you need to choose the hemp you need. I would recommend that you consult a specialist. At the end of the post there are also some distributors who have heather in their product portfolio and can give you the information you need.
4/Am I trained to use a hearse?
As we have a lot of wood enthusiasts reading our site, many of them interested in setting up a small workshopI have to say these things. Some of these machines seem very handy and easy to use. However, they are not little machines that you start playing with and immediately achieve impressive things. When the hearse is used by inexperienced people it can result in bent faces and even accidents. That's why experts recommend that you understand the operational aspects of the machines as well as possible and practice before you start working on important projects. This way you avoid extra costs for troubleshooting.
5/Where do I buy?
In order to show you a few options for hedges, we have asked a few distributors for their offers in this regard. As far as I noticed all the machines shown contain both planing and thicknessing operations.

East European Trade
EET proposes mwood shavings - abricht MARTIN mod. T 54
MARTIN is a German manufacturer known for the highest quality of its cars. In addition to the much appreciated circular knitting machines, MARTIN also offers the perfect machine for planing, say EET. The T54 has been designed to do two things very well: to machine workpieces perfectly and to execute angled edges quickly and safely. The slide line moves smoothly and easily, facilitating fast and precise operation with the linear assist. The abricht stopper with roller guides glides easily and evenly on the hardened rails, giving the user the same working comfort decades later as on the first day. Shearing operations can also be carried out quickly with the 90° and 45° angle adjustment wheel.
As with all MARTIN premium machines, the machine's chassis consists of a MARTIN-specific reinforced concrete alloy that guarantees optimum vibration absorption and absolute stability. This special construction drastically reduces noise and provides a quiet working environment.
Some of the technical details of the MARTIN T54:
Engine power: 5.5 kW (7.5 hp)
Working width: 500 mm
Max. planing thickness / pass: 8 mm
Max. feed table length: 2000 mm
Length of outlet table max 1580 mm
Weight: 1200 kg
Instead of the standard TERSA knives 3 rows of special Xplane planer knives can be chosen. They impress both with their increased quietness and ease of cutting without stressing the machine engine, even at greater cutting depths. The cutting quality of the MARTIN XS-Cut knives, especially for hard-to-process materials, is truly outstanding, thanks to the pull-cutting motion. This increases the service life of the knives by up to 20 times.
The rotation speed is 6000 rpm, so you have the optimum cutting speed.
In order to always have the controls at hand the control panel slides together with the abricht stopper. The grinding depth is digitally displayed and adjustedeasily and accurately with a potentiometer-type knob.
Protective deviceSUVAMATIC protects the entire shredding area with a single layer of protection.
Thanks to this helpful stopper you can also machine small and narrow workpieces. An important feature for working safety.
There is much more to be said about the heather. I hope I have aroused your curiosity to find out more on the subject.

Hello. All esteem for the magazine dedicated to the wood industry that you manage.
I have, however, a few comments, in particular, to the author of the article about the wood straightening operation (the one concerning the "heather"):
1. We are Romanians and we MUST use the Romanian language, without using "Englishisms" (?). Language is created by each people, so that its citizens can understand each other and this principle MUST be the LAW. All the more so as we are addressing a wide audience of Romanians, on a professional website.
2. We are professionally responsible for any statement or information we transmit to the public, especially through mass media. The responsibility lies in the fact that the user wants to be informed, BUT CORRECTLY.
3. In a school (regardless of its rank) various professions are taught (nowadays... not so much) and according to fundamental principles, various expressions, codes, standardized names are used, so that specialists and not only, can understand each other. If there are certain regionalisms, abbreviations or other names, coming from another language, these should NOT be promoted in professional expositions (possibly in parenthesis).
3.1 There is no such thing as "abric" or "abricht" for a Roman professional, there is a straightening machine which, depending on the straightening width, is assigned a code (e.g. 200; 250; 300; 400; 500, etc.) representing the width of the machining table - the symbol being MI 300 (e.g.). The operation is called STRAIGHTENING and not RENDERING.
3.2 There is also no such thing as a "thickness machine", there is a THICKNESS MILLING MACHINE (MRG), which performs the operation of uniforming the thickness of the processed piece of wood (i.e. constant thickness along the length). As with the Straightening Machines, these too have a code representing the maximum width that the machine can process (250 mm; 300 mm, etc.) i.e. MRG 400.
3.3 There is no such thing as a "thickness planing machine". there is a UNIVERSAL MACHINE FOR MACHINING (abbreviated: MUT) and they are machines intended for small workshops with small and diversified series production, comprising several processing modules such as: Straightening, Thicknessing, Milling (bottom milling cutter - equivalent to normal milling machine - MNF), Horizontal boring and boring (equivalent to MGSO - Horizontal boring and boring machine) or/and circular boring machine. These being machines with 2; 3; 4 and/or 5 types of woodworking operations.
4. In conclusion, respecting the fundamental principles of communication and expression within a profession, I ask you to respect them. Attention: those of us who answer or address the general public are also responsible for their education (professional education). Otherwise, we end up that the carpenter from Ardeal cannot get along with the carpenter from Dobrogea, one using "abric" or "banzic", and the other who knows what Turkish or Tatar name.
5. With all esteem to a professional school. Even amateurs should be instructed to use professional standard names.
Thanks for the completions
