A machine for producing cushioning product is provided which allows a user to select a length of product to be produced from a plurality of selectable lengths. The machine (10) comprises a frame (12), a plastic sheet supply assembly (14) mounted on the frame (12), a forming assembly (18) mounted on the frame (12) downstream of the plastic sheet supply assembly (14) which forms the plastic sheet (16) into a tube (20) with the lateral edges of the plastic sheet (16) overlapping, a pulling assembly (40) mounted on the frame (12) downstream of the forming assembly (18) which pulls the plastic sheet (16) from the plastic sheet supply assembly (14) to and over the forming assembly (18), a first heat sealing assembly (90) mounted on the frame (12) downstream of the forming assembly (18) which is selectively activatable to longitudinally heat seal the overlapping lateral edges of the tube (20) together a selected length from a continuous plurality of selectable lengths, and a second heat sealing assembly (140) mounted on the frame (12) downstream of the first heat sealing assembly (90) which transversely heat seals the tube (20) at each end of the longitudinal seal formed by the first heat sealing assembly (90) to thereby form an air pillow. |
