Packaging apparatus
DCFirst Claim
1. A stripping and sealing assembly for packaging apparatus, said apparatus including a product delivery head, a drive assembly to pass a tubular bag material past said delivery head so that product delivered from said head is located within said tubular bag material, said assembly including a pair of opposing sealing and stripping means located on opposite sides of said bag material at a position downstream of said delivery head relative to the direction of movement of said bag material through said apparatus, said sealing and stripping means being adapted to cooperate to sealingly close portions of said bag material and strip same, a first arm means supporting one of said sealing and stripping means, a second arm means supporting the other sealing and stripping means, and wherein the arms are rotatably driven in synchronism in opposite directions about spaced parallel axes extending generally transverse of the direction of movement of said bag material so that prior to sealing said bag material said sealing and stripping means are moved along said bag material to strip same.
