divided scissor pieces 48, 49, 50 with any shape Bring the strip models to the true-to-shape system and then also with the contact pressure required for gluing works.

According to an exemplary embodiment of the inventive concept, the support rods 54, 55 are made from Pig. 3, arranged in a crossed manner that the rod 54 acting on the left scissors (43) finds its puss point 56 on the right and is cranked at the top so that the rods do not interfere with each other when the scissors close. In the outer support tube 64, which is screwed to the base piece 56 carrying the bearing head 58, the compression springs 66 extend when released, that is, lengthen the cranked upper support rod 68 _{O. In the} example shown, the pedal group consists of a weaker guide spring 70 and a stronger pressure spring 71 ° When the bale shears 40, 41 close, the pressure spring 71 is tensioned after the extension spring 70 has blocked. The rough adjustment of the pedal effect takes place when adjusting the vertical supports 30,31. With the help of the knurled nut 72, the spring preload can be readjusted within limits.

The tweaking is done in the above-described tip interposing device after it has been pushed over by the push rod 74 and fork 75 onto the pair of sliding scissors 14, 15 initiated at the top. The point of rotation of the tip scissors 34 is positioned in the longitudinal axis of the groin on the groin pull shifted, wherein the arcuate-like guide grooves 76, in the curve piece 36, 57 guide a forward and pivoting movement of the Spitzenacheren, but also at the same time on the oil-steering

pair of visors 16, 17 via roller bolts 78 and guide grooves 80, 81 act. The joint scissors 40, 41 are at the The outer side 82 is shaped like an arc of a circle and is thus approximately perpendicular to the strip axis on a curved piece 84 32 to retracted. The roller bolt 78 connecting the two scissor parts is made up of a straight line and a Circular arc piece existing curve slot 90 out. The translational movement described so far runs in one Level and would lead to the horizontal support of the tip scissors on the bottom of the groin without any further aids, the Pointed scissors are shaped on their run-up edges 92, 93 in such a way that the lasting allowance is encompassed by them.

For pinching the joint and ball area, however, special, more extensive measures must be taken, which, as already said, “consist in the arrangement of spring-loaded, cross-acting stanchion members 54, 55. During the movement process described above, the support rod 54 is inevitably connected to the link 50 ₁ . on which it is attached with its upper ball joint 52, initially moved in a circular arc-shaped flat path, the cranked support rod 68 being able to be pushed in shortened against the force of the extension spring 66. At the moment when the resultant of the translationally effective force arrow and the retroactive spring force lifts out of the plane, the scissor link 50 follows further progression of the postponing movement is reinforced, but only for as long as the elaborated link joint flanks 94, 96 FIG. 9 allow.

According to the invention, these are the intended angle of rotation beveled accordingly and have the task of moving away from the support rod 68 to the tip of the shoe - to the in the translation plane remaining scissor link 47 to lift the next link with each other, ZoB. Link 50 lifts the limb 49 and this again limb 48 up to this point where the inguinal rupture or ball rounding gets a full system * see Figs. 4, 5 and?.

The bale shears are for example by the bolts 44, 45, 46 (Pig. 5 and 7) pivotable about them, with protruding Joint pieces connected by the movable scissor link 48 grip the fork-shaped part of the fixed scissors. The top view of the raised scissors (Fig. 5) shows in line 60 the limit of the recess caused by the lasting allowance to the edge of the groin Scissors. In the section through the link 50 (Fig, 6) it can be seen that this recess 92 extends from the line 60 starting to the rounding 93 Mn on the slide-on side, this creates a stronger slide-on effect With the part 88 hinged from below, it becomes the most extreme Joint member 50 connected to the support rod 68, under which The closed joint scissor surface 114 shown in section in FIG. 7 is achieved. At the edge 86 is when the closing joint scissors with the discontinued Tip 85 of the first link 47 move under the tip scissor plates 38 and 39, a transition-free adaptation to this achieved.
