An orbital stretch wrapping apparatus, comprising:
- a base frame;
- a circular ring mounted on the base frame and rotatable with respect to the base frame about an axis of rotation;
- a stretch film dispenser mounted on the circular ring and rotatable with the circular ring about the axis of rotation, the stretch film dispenser having in between a pair of mounting flanges of the stretch film dispenser:
- (a) a subframe fixed to the circular ring;
- (b) a roll of stretch film mounted to the subframe and rotatable with respect to the subframe, the roll of stretch film being a continuous piece of the stretch film;
- (c) a first feed roller mounted to the subframe and rotatable with respect to the subframe, the first feed roller engaging the stretch film of the roll of stretch film and rotating at a roller speed during rotation of the circular ring at a set speed;
- (d) a second feed roller mounted to the subframe and rotatable with respect to the subframe, the second feed roller engaging the stretch film of the roll of stretch film and rotating at the roller speed during rotation of the circular ring at the set speed;
- and
- (e) a brake member in a continuous relationship with the first feed roller and the second feed roller, the brake member capable of adjusting the roller speed while the circular ring rotates at the set speed, the brake member further includes a compression spring disposed on a pair of guide pins attached to a braking disc.
