Package wrapping machine

摘要

A package wrapping machine which has a frame supporting a power driven rotary horizontal shaft with a turret plate member on the end of the shaft supporting spaced clamp banks, a positioning blade is placed between the said clamp banks for positioning the package components prior to clamping, a stack of package components is clamped between the clamp banks by fluid power cylinders on the turret plate moving one clamp bank toward the other. The end of an elastoplastic wrapping or web extending from a clamp roll on the frame is moved under one clamp bank by insertion of the packages to be wrapped into position. The web is then clamped by the clamp bank to the package components when they are rotated a predetermined number of rotations to effect the wrapping of the package components; a film cut-off means severs the web of wrapping from the wrapped package following the wrapping of the package and a pusher plate between the tine banks is extended by a cylinder to push off the completed package from between the clamp banks and the positioning blade.
