Abstract
This invention relates to a novel lifter construction for rolling filled cans. It is designed to allow a lifter plate to effect relative rotation with respect to a lifter body to be forcibly driven in order to introduce the merits of the free rotation system into a lifter of prior art forced driving system. To this end, there is proposed a construction wherein the lifter plate is driven by a clutch and the clutch is disengaged with lifter pressure, and a construction wherein the lifter plate may be rotated through a given angle on the plate supporting bed. Preferably, a detector is provided to detect an abnormal rolling of cans or the like.
