FILM TENSION APPARATUS AND SUPPLY ROLL SUPPORT FOR STRETCH WRAPPING MACHINES

摘要

A film dispenser (12) for stretch wrapping machines(10) includes at least one roller (18) and a first brake (42) engageable with a braking surface (52) the one roller. The first brake (42) may include a flat brake pad (62) that is pivotally movable for engagement with the braking surface (52), and is adjustable between a first configuration engaged with the braking surface (52) and applying a first braking force, and a second configuration disengaged from the braking surface (52) or only minimally engaged with the braking surface (52) such that any braking force applied is substantially less than the first braking force. A supply roll (18) support for a film dispenser (12) includes an elongate post (32) sized to receive a roll of film (14) thereon, and a pliable sheet (160) coupled with the outer peripheral surface (150) of the post (32) and extending around at least a portion of the outer peripheral surface (150).
