Device for serrate cutting between two pairs of top and bottom knives and for glueing the ends of veneer

摘要

The invention relates to a device for serrated cutting, between two pairs of top and bottom knives, of the ends of thinning bands, and for gluing these ends using, inter alia, a shield on which the pressure required is exerted by a hammer of a press which can be displaced upwards and downwards and is held for this purpose in a bridge which is vertically displaceable, characterised in that it comprises the following elements: a) means for locking the hammer (13) of the said press relative to the said bridge; b) top and bottom knives which cut the thinning bands at different heights; c) means for bringing the said hammer (13) to its rest point when it is unlocked relative to the said bridge (2); d) a pneumatic cylinder (28) for drawing the said bridge (2) downwards; e) means for neutralising the pressure exerted by springs on the bottom knives.
