ABSTRACT:
A method and device for end closing tubular wrappings of products, whereby the arms of a scissor-type parting device, once inserted in a closed position inside an end portion of a tubular wrapping, are allowed to part, and are pushed by springs into a fully open position throughout an extraction stroke to crease the end portion and enable the end portion to be pressed taut and accurately by the opposing thrust of two folding-sealing members.
