Abstract

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.

First claim

What is claimed is:

1. A dispenser for dispensing flexible material from a coil having a core, comprising:
a frame having an axle;
a coil carriage mounted to the frame, the axle defining an axis of rotation about which the coil carriage rotates, the coil being securable within the coil carriage for rotation therewith, the coil carriage comprising a front guard and a rear guard and a plurality of spokes extending radially relative to the axle from a first radially inner position to a second radially outer position;
coil retaining elements mounted to the carriage to secure the coil between the front and rear guards, each coil retaining element mounted to a respective spoke of the plurality of spokes and projecting in an axial direction outward from a radial position between the first radially inner position and the second radially outer position on its respective spoke, the coil retaining elements including a plurality of fixed coil retaining elements each fixed relative its respective spoke, and an adjustable coil retaining element having a clamp fitted into a slotted opening in one of the spokes of the plurality of spokes and movable along its respective spoke between the first radially inner position and the second radially outer position to selectively engage the core, wherein in the second radially outer position the adjustable coil retaining element abuts against the core; and
a brake/payout assembly operably mounted to the frame and moveable toward and away from the coil carriage, the brake/payout assembly being biased toward the coil carriage for engagement therewith, the brake/payout assembly including a contact roller and a feed roller movable toward and away from the contact roller, the feed roller being biasedly mounted toward the contact roller, the contact roller and the feed roller defining a nip region therebetween;
wherein the flexible material is configured for receipt in the nip region as it is paid out from the coil, and
wherein the contact roller engages the coil carriage to slow rotation of the carriage.

2. The dispenser in accordance with claim 1 wherein the dispenser is formed as a cart.

3. The dispenser in accordance with claim 1 wherein the brake/payout assembly engages one or both of the front guard and the rear guard.

4. The dispenser in accordance with claim 1 wherein the brake/payout assembly is pivotally mounted to the frame.

5. The dispenser in accordance with claim 1 including at least three coil retaining elements.

6. The dispenser in accordance with claim 1 wherein the contact roller includes one or more contact pads on a periphery thereof for contact with the one or both of the front and rear guards.

7. The dispenser in accordance with claim 1 wherein one or both of the contact roller and the feed roller are formed from a low friction material.

8. A dispenser for dispensing flexible material from a coil, the coil having a core, the dispenser comprising:
a frame;
a coil carriage mounted to the frame, the frame defining an axis of rotation about which the coil carriage rotates, the coil carriage having first and second guard elements for securing the coil therebetween and a plurality of spokes extending radially relative to the axis of rotation from a first radially inner position to a second radially outer position, the coil carriage configured for rotation on the frame about the axis of rotation;
at least three coil retaining elements to secure the coil in the coil carriage, each coil retaining element mounted to a respective spoke of the plurality of spokes and positioned between the first radially inner position and second radially outer position, and at least one of the coil retaining elements being adjustable along a portion of one of the spokes of the plurality of spokes and movable in a radial direction relative to the axis of rotation between the first radially inner position and the second radially outer position, the at least one coil retaining element having a clamp fitted into a slotted opening on the spoke and adjustable so as to selectively engage a portion of the core, wherein in the second radially outer position the adjustable coil retaining element abuts against the core;
a brake/payout assembly operably mounted to the frame and moveable toward and away from the coil carriage, the brake/payout assembly including a contact roller and a feed roller movable toward and away from the contact roller, the feed roller being biasedly mounted toward the contact roller, the brake/payout assembly engageable with the coil carriage to slow rotation of the carriage, the brake/payout assembly including a payout portion through which the flexible material is captured during payout.

9. The dispenser in accordance with claim 8 wherein the brake/payout assembly is pivotally mounted to the frame and biased toward the coil carriage.

10. The dispenser in accordance with claim 8 wherein the brake/payout assembly includes a feed roller biasedly mounted toward a contact roller and defining the payout portion therebetween, and wherein the flexible material traverses through the payout portion as it is paid out from the coil.

11. The dispenser in accordance with claim 10 wherein the contact roller includes one or more contact pads on a periphery thereof for contact with the coil carriage.

12. The dispenser in accordance with claim 10 wherein one or both of the contact roller and the feed roller are formed from a low friction material.
