Cart type strap dispenser with improved strap brake/payout assembly

摘要

A dispenser is used for dispensing flexible material from a coil. The dispenser includes a frame, a coil carriage mounted to the frame and a brake/payout assembly mounted to the frame. The frame defines an axis of rotation about which the coil carriage rotates. The coil is securable within the coil carriage for rotation with the carriage. The brake/payout assembly is operably mounted to the frame and is moveable toward and away from the coil carriage. The brake/payout assembly is biased toward the coil carriage for engagement with the carriage. The brake/payout assembly engages the coil carriage to slow rotation of the carriage and includes a nip region through which the flexible material traverses during payout.
