A web tensioning device to maintain a pre-selected web tension during web delivery and web roller take-up. The device comprises a web pressure sensing roller, tension pre-selection and conditioning circuitry means associated therewith. A motor controller responsive to condition circuitry input selectively controlling a supply roller.

Web tensioning device

A web tensioning device to maintain a pre-selected web tension during web delivery and web roller take-up. The device comprises a web pressure sensing roller, tension pre-selection and conditioning circuitry associated therewith. A motor controller responsive to condition circuitry input selectively controlling a supply roller in a closed loop self-regulating system to maintaining desired film tension despite input roller variations.

An apparatus for dispensing and applying stretchable adhesive tape to unitize a multiple unit load. The apparatus includes a tape dispenser head on a movable carriage that pre-stretches a narrow band of adhesive tape around a load positioned on an adjacent turn table in a spiral wrapping configuration as the movable carriage ascends and descends vertically in relation to the load while a secondary movable carriage having a tape supply moves within the tape dispenser carriage. Textured pre-stretch rollers and adjacent guides elongate and guide the adhesive tape within the tape dispensing carriage.

Stretch wrapping tape dispensing apparatus

An improvement in a stretch wrapped braking apparatus used to restrict a roll of stretch material on a single roller stretch wrapping apparatus. The improved brake uses a modified controlled magnetic motor to impart braking effect indirectly to the roll of stretch material as it is pulled therefrom by a rotating load to be wrapped.
