INRICHTING VOOR HET VERPAKKEN VAN IN EEN CONTINUE STROOM TOEGEVOERDE VOORWERPEN.

摘要

An apparatus for packing articles having at least two sealing rollers mounted for rotation by a mechanism so that the rollers are rotated with a non-constant rotational velocity. The mechanism comprises a crank arm and a coupling member, and a driving cam is provided which is shiftable in a slot formed in a follower member extending parallel to the crank arm. The design is such that every time the axis of rotation of the crank arm has moved along a complete circular path the crank arm is rotated at least one time over 360 DEG .
