Abstract
An improved cam mechanism bends carton blanks fed from the magazine of a packaging machine. The carton blanks each have a gripped portion attached to the packaging machine and a bendable portion extending from the gripped portion. The cam mechanism includes a rotatable shaft mounted on the packaging machine and at least one cam member mounted on the shaft. The cam member has a plurality of longitudinally extending side walls and apex portions interconnecting the side walls. Rotating the shaft about its longitudinal axis positions the side walls adjacent the gripped portions of the carton blank, and the apex portions radially displace the bendable portions of the carton blanks as the carton blanks are fed from the magazine.
Claims5
An apparatus for bending carton blanks fed from the magazine of a packaging machine, each of the carton blanks having a gripped portion held by the packaging machine and a bendable portion extending from the gripped portion, the apparatus comprising:
- (a) a rotatable shaft mounted on said packaging machine, said shaft having a longitudinal axis;
- (b) at least one cam member mounted on said shaft, said at least one cam member having a plurality of longitudinally extending side walls and apex portions interconnecting said side walls;
- and
- (c) means for rotating said shaft about its longitudinal axis such that said side walls are adjacent the gripped portions of the carton blanks and said apex portions radially displace the bendable portions of the carton blanks as the carton blanks are fed from the magazine.
