Abstract: A package wrapping machine has a frame supporting a power driven rotary horizontal shaft with a turret plate member on the end of the shaft supporting two spaced tine banks; a stack of package components is clamped between the tine banks by pneumatic cylinders on the turret plate moving one tine bank toward the other. The end of a plastic film web W extending from a roll on the frame is clamped to the package components when they are rotated a predetermined number of rotations to effect the wrapping of the package components; a hot film cut-off means severs the web of plastic film from the wrapped package following the wrapping of the package and a pusher plate between the tine banks is extended by a cylinder to kick the completed package from between the tine banks, control means actuates the clamping means, rotary member, said film cut-off means and pusher plate in timed sequence.

Abstract: Two embodiments, a towed embodiment and a self-propelled embodiment, of a compost machine for shredding, mixing and aerating decomposable and non-decomposable waste material deposited in strips on large sites are disclosed. Both embodiments of the compost machine of this invention include a frame-suspension member, a rotary member, a plurality of replaceable teeth carried by the rotary member, a folding protective shield system, a pair of hydraulic motors and a prime mover. In both embodiments the hydraulic motors are mounted inside the rotary member, one at each end and are driven by the prime mover through a shock-protective coupling arrangement.
