ABSTRACT:
A semi-automatic T-shirt bag bagging rack and bags for use therewith. The bagging rack has a stationary rear wall with two spaced apart hooks and a tab receiving member. A support base is attached to the stationary rear wall. A movable front frame member moves between a first position distant from the stationary wall and a second position adjacent thereto. The movable front frame member has an upper planar member which is substantially parallel to the stationary rear wall and has a tacky rubber sheet member affixed thereto facing the stationary rear wall. A stack of T-shirt bags having a central tab with a central tab slit and a tab tearing slit cut therethrough and "C"-shaped cuts located near the inside edges of the handles are first loaded on the bagging rack by slipping the central tab slit of the stack of bags over the tab engaging member and by looping the "C"-shaped cuts on the handles onto the hooks on the rear wall. The movable front frame member is moved forward to bring the tacky rubber sheet member into contact with and to adhere to an upper portion of the top layer of plastic of the top bag. Thereafter, the movable wall is moved backwards. This tears the handles free from the hooks in the vicinity of the "C"-shaped cuts and tears the top layer of plastic as the tab tearing slits, thereby opening the bag.
