Detachable knife block attachment is to be provided for a ser.-Furthermore, two separate extension devices are required for the long knife scissors, in which each knife block consists of 5 upper knife block ₍ , and the lower knife block then a feed bar with inserted cutting knife and each in a knife block carrier Hch, which usually also can only be clamped in a dovetail-like manner when actuated one after the other. characterized in that both in the present invention, the task is to- the lining strips (3,9) als.auch with the knife io reasons to improve a scissor knife of the initially described block carriers (1,7) engaging behind clamping type to the effect that the changing surfaces (4,10) in the knife longitudinal direction as a rule - The knife blocks can be placed on top of one another without difficulty even under tight spaces. Above all, have solba gaps (22,23), the width of which also reduces the changing times and which is larger than that of the clamping surfaces, and that the 15 lining strips (3,9) separated for the upper and lower knife block in the longitudinal direction of the knife around the changing device be avoided,

This ensures that the lower is cash.

B. can be locked in knife direction, a production line can be avoided and thereby the mandrels also form the stop for Knife blocks prepared accordingly for storage 60 the knife block position in which his teeth with the can be held. It is inevitable, however, to disengage the lower scissor saddle. that after several hours of uninterrupted operation. From this position the lower measuring a standstill has to be accepted in order to then cut the block across the knife direction by to be able to change the knife blocks. This pull back the mandrels lift out, whereby The process is due to the considerable weight of the 65 tooth side facing away from the receiving mandrels, Knife blocks are not only difficult to make, so that the upper knife block is now inserted into them rig, but because of the spatial expansion it can also become very bulky. The space required to remove the knife blocks is made possible.
