ABSTRACT:
The pre-grooved plates e.g. of chewing gum are advanced over a stationary breaker edge into the path of a rotating, polygonal (preferably triangular) breaker shaft whose apices form breaker edges which rotate past the stationary breaker edge. Each facet of the shaft is provided with a stop positioned to be engaged by the leading edge of the advancing plate. The distance across a facet from the respective stop to the respective rotating breaker edge is equal to the width of a strip to be broken from the plate at the next groove in the plate. The axis of rotation of the breaker shaft is transversally displaced from the level of the plate, by an amount sufficient to provide the rotating breaker edge, at the site where the breaking occurs, a velocity component in the direction of advance of the plate which approximately matches the velocity of advance of the plate. Accordingly, the advance and rotary breaking may proceed continuously.
The strip which has been broken off is moved by the respective facet, transversally, to a strip support virtually parallel to the position of the strip at the moment of break and is then transferred from the strip support to a packaging machine before the respective rotating breaker edge has rotated to the level of the strip support.
