Abstract

Abstract In an apparatus for cutting portions such as labels or tickets from a continuously moving web, the web is passed between a blade and a co-operating support member. As the web moves past the blade, the blade is displaced during the cutting operation in the same direction as the web and synchronously therewith, but over a shorter distance than the length of the portion to be cut out. The blade is then disengaged from the web and returned to its initial starting position. The support member may also be displaced in the opposite direction to the movement of the web and blade during the cutting operation.

Claim 11
Dependent Claim 44 words
Apparatus as set forth in claim 1 including a web guide roller disposed adjacent said support roller and adapted to be driven in rotation in the cutting operation, in dependence on the speed at which the roller is displaceable with respect to the web.
Claim 12
Dependent Claim 73 words
Apparatus as set forth in claim 9 including at least two driven web guide rollers each arranged at a respective spacing from the blade, gear wheels adapted to drive said driven guide rollers and said support roller, and a common flexible elongate drive means interconnecting said gear wheels and extending parallel to the path of the web in the region in which the drive means moves in the same direction as the web.
Claim 13
Dependent Claim 102 words
Apparatus as set forth in claim 7 wherein said second mounting means includes a carriage carrying the blade and provided with an elongate recess means which extends perpendicularly to the path of movement of the blade, and further including a drive means, a drive member for displacing said carriage and comprising a double-armed lever, a drive member on a first arm of said lever engaging into said recess means, and a cam follower disposed on the second arm of said lever and co-operable with a cam means on a rotatable member, the cam means corresponding to the desired movement of the blade.
