This is then between, and see the working jaws of a press brought, which Fig. 4 is a side view of the last phase press the claws of the claw plate into the wood. the production of the butt joint can be seen. This compression can either be done at any time individually, or - depending on the size ao preferably using a claw plate and construction of the press - at all joints according to fig. 1 made of soft steel and a thickness of done at the same time. perform about 1.2mm because in this case Other known methods use different claw plates during the preliminary knocking in at those, with even greater technical effort, bends condensate points 8 sufficiently to only clamp the hydraulic presses on the plateaued ones, which clamp into the material of the wooden components 6 both for the fixed corners 10 Wooden components as well as to be knocked in,

To carry out the method according to the invention It has now been found that these can be known to become two together th manufacturing process of connections between connecting wooden components 6 - here for example Timber beams can be improved significantly. 30 two wooden beams - butted with their end faces 12. The object of the invention was to provide a method on this arrangement, a claw plate 5 is so find, with the roof rack, frame rack placed that their claws 15 on the tops and have other wooden rod constructions made, the wooden support 6 sit on it.

The wood driving in the claws and the back and forth components 6 can then be transferred automatically to a roller press, either by hand or by moving the wooden components, which requires more manual work, with the help of all of the other claws 15 which are embedded in the wood using claw plates 5 in use at present for the final connection of the clamping devices and presses for the production of wooden components 6.
Butt connections serve. Nevertheless, the un- In F i g. Fig. 4 shows an example of such a roll cost for the press equipment required for manufacture. Two in the direction indicated by the arrows as well as the costs for the essential direction indicated here, or lent thinner claw plates reduced. Rollers press the claws 15 of the two claws - this makes it possible for smaller entrepreneurs to see the wooden components 6 in the wood to produce a butt joint between roof girders and the like with relatively little.
