ABSTRACT:
A machine to apply strips or webs of heat-sealable and/or heat shrinkable material around coiled rolls of sheet material to either band or wrap such rolls, or shrink such bands or wrapping web into close contiguous engagement with said rolls to prevent uncoiling of the same. The machine includes means to relax the tension on the strips or webs when the same are about to be heat sealed to encircle coiled rolls by means of anvil and heater bars which cooperate to engage said strips or web when encircling the rolls and heat-seal the same and simultaneously sever the encircling portions from the supply and also re-connect the severed portions by fusion to position the same across the path of the rolls through the machine for engagement by the rolls. Pusher means also push the coiled rolls into engagement with re-connected strips or web by means of guide mechanism for the pusher means which moves it horizontally. A removal conveyor also operates in association with a stationary member which supports the rolls while being encircled with said strips or web to remove the banded or wrapped rolls from the heat sealing means to carry them to additional heating means to heat-shrink the bands or wrapping webs around the coiled rolls.
