摘要： A film delivery system for use with plastic film wrapping apparatus for wrapping prestretched plastic film around a palletized load or article disposed at a wrapping station comprises a brake hub or pulley upon which a roll of plastic film material is mounted, and a single dancer or idler roller mounted for linear reciprocating movement upon a mounting plate and around which the plastic film material is routed from the roll of plastic film material to the load or article being wrapped. A brake band is disposed around the outer peripheral surface of the brake hub, and one end of the brake band is connected to a brake arm, while the other end of the brake band is connected to a brake adjustment spring. The brake arm is also connected to the single dancer or idler roller such that depending upon the linear disposition of the single dancer or idler roller during a plastic film wrapping operation, different braking or tension forces are impressed upon the brake hub and the plastic wrapping film material.
