  • Roll-capping machine and method
    Patent number: 4574458
    Abstract: Apparatus and method for inserting a plastic cap into the open end of a roll. Spaced rolls are moved downstream along a continuously moving conveyor and are lifted from the conveyor for capping. A cap gravity falls down a chute to a loading position where it is picked up by a plunger and seated in the end of the lifted, aligned roll. The capped roll is then returned to the conveyor.

  • Roll wrapping or banding machine
    Patent number: 3990215
    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.

  • Seal temperature control means for curtain-type wrapping machine
    Patent number: 3965333
    Abstract: Temperature control means for a curtain-type wrapping or banding machine to prevent excess ambient temperature thereon by employing switch-actuating means responsive to even very small changes in the expansion and contraction of the elongated heating element on the heater bar of the machine which co-acts with the anvil thereof to effect sealing of either a web or bands of thermoplastic synthetic resin material around various types of objects of various sizes and also re-constitute the web or bands into continuous form incident to severing the sealed web or bands from the supply material.
