Abstract: A multiple coil dispenser supports a pair of coils for dispensing a flexible material from one of the coils. The dispenser includes a frame and at least one coil support for supporting the coils for rotation. A fixed arm is mounted to the frame and includes a plurality of rollers positioned longitudinally therealong. A movable arm is pivotally mounted to the frame for movement toward and away from the fixed arm. The movable arm has a plurality of rollers positioned longitudinally therealong and is biased away from the fixed arm. A bifurcated chute directs the strapping material from one of the coils to the arms. A brake assembly is operably connected to the movable arm between an engaged position when the movable arm is moved away from the fixed arm and a disengaged position when the movable arm is moved toward the fixed arm. A space between the fixed arm and the movable arm defines an accumulation region that varies in size as the movable arm moves toward and away from the fixed arm.

Abstract: A strap path guide cover, comprising part of the outer housing cover of a strapping machine, is pivotally mounted such that it may be rotated away from the housing of the strapping machine to expose a strap path. The cover defines parts of numerous elements of the strap path created through the head of the strapping machine.
