ABSTRACT:
A machine for packaging sundry articles between two weldable plastics material sheets is disclosed, in which provision is made for the formation of a top sheet loop to cope with different tallnesses of the articles as they are being packaged and sealed between the plastics sheet: undue sheet tensions are prevented as well as undue slackening of the sheet.
Waste of plastics material is also efficiently done away with.
