Definitions
- the present invention relates generally to systems, apparatus and methods for securing the free end of wound cable. More particularly, the invention is a system and method for securing the free end of a length of an elongate, flexible cable that is wound onto a spool by a spooling machine. The free end of the cable is secured using stretch wrap that is automatically applied to a spool of wound cable as the cable is being cut so that the leading end of the stretch wrap is nipped between the spool of wound cable and the free end of the cable.
- the stretch wrap system is mounted horizontally and movable in a transverse direction to service at least two cable spooling stations on a spooling machine.
- Spooling machines are known for automatically winding a length of elongate, flexible cable, for example coaxial cable or fiber optic cable, onto a spool and for automatically applying stretch wrap to the spool of wound cable.
- a spooling machine including fully automatic dual take-ups for on-line or off-line packaging of cable products is available from the Hall Industries division of the MGS Group having its corporate offices located in Rome, New York, USA.
- the MGS/Hall spooling machine includes two winding stations for winding a length of cable onto a spool and for applying a relatively thin layer of stretch wrap to the spool of wound cable to secure the free end of the cable onto the spool.
- Each winding station has a spooling head that is provided with a positive automatic stretch wrap applicator.
- the stretch wrap applicator operates to apply the stretch wrap to the spool of wound cable so that the starting end of the stretch wrap is positively pinched under the free end of the cable just prior to the conclusion of the winding cycle.
- the automatic stretch wrap applicator provided at each winding station of the MGS/Hall spooling machine includes two clamps and a push-down roller.
- the first stretch wrap clamp operates to pull the starting end of the stretch wrap from a stretch wrap roll to a position that is relatively close to the spool of wound cable.
- the push-down roller next operates to move the stretch wrap to the opposite side of the wound cable.
- the second stretch wrap clamp then operates to grab the stretch wrap from the opposite side and to pull the stretch wrap back across the spool of wound cable.
- the MGS/Hall stretch wrap applicator requires an excessive number of separate components, which results in high cost and reduced reliability of the applicator.
- the MGS/Hall stretch wrap applicator does not pull the stretch wrap between layers of the wound cable. Therefore, the relatively thin layer of stretch wrap can slip on a wound cable having an excessively smooth or slick jacket, and as a result, not be pulled around the spool of wound cable.
- the MGS/Hall spooling machine utilizes two vertically oriented spooling heads and requires a separate stretch wrap applicator for each spooling head. Since the spooling heads are oriented vertically, the free end of the cable can bend downwardly under the influence of gravity relative to the feed direction of the stretch wrap.
- the free end of the cable can extend outwardly from beneath the stretch wrap and potentially snag causing premature removal of the stretch wrap.
- the use of a separate stretch wrap applicator for each of the two spooling heads unnecessarily duplicates components of the spooling machine and increases acquisition, maintenance and operating costs.
- the present invention is a system and method for winding a length of cable onto a spool and automatically applying stretch wrap onto the spool of wound cable to secure the free end of the cable on the spool. More particularly, the invention is a stretch wrap applicator for a spooling machine having two spooling heads and a method for applying stretch wrap onto a spool of wound cable at each spooling head to secure the free end of the cable on the spool.
- the invention is embodied by a system including a spooling machine having at least one spooling head for winding a length of an elongate, flexible component onto a spool and a stretch wrap applicator configured for and operable for securing a free end of the elongate, flexible component on the spool with stretch wrap.
- the stretch wrap applicator pinches the stretch wrap between the free end and outermost windings of the elongate flexible component wound on the spool.
- the spooling machine has two spooling heads and the stretch wrap applicator is mounted on the spooling machine for transverse movement relative to the spooling heads.
- the spooling machine may have a rail and a drive mechanism and the stretch wrap applicator may be operably coupled with the drive mechanism for transverse movement along the rail relative to the two spooling heads.
- the two spooling heads of the spooling machine may be positioned at transversely spaced-apart locations along the rail and the stretch wrap applicator may be operable for transverse movement between the spooling heads.
- the stretch wrap applicator includes a pulling clamp configured for and operable for being moved from an initial position around the free end of the elongate, flexible component wound on the spool and into engagement with a starting end of the stretch wrap.
- the pulling clamp is further configured for and operable for moving back to the initial position while gripping the starting end of the stretch wrap such that the stretch wrap is disposed between the free end and the outermost windings of the elongate, flexible component wound on the spool.
- the pulling clamp is further configured for and operable for moving downwardly relative to the elongate, flexible component wound on the spool so that the stretch wrap is pinched within a nip defined between the outermost windings of the elongate, flexible component and the free end of the elongate, flexible component.
- the invention is embodied by a stretch wrap applicator for a spooling machine having at least one spooling head.
- the stretch wrap applicator includes a housing, a roll of stretch wrap disposed within the housing and a pulling clamp configured for and operable for gripping and pulling a starting end of the roll of stretch wrap so as to position the stretch wrap between a spool of wound cable having outermost windings and a free end of the cable wound on the spool.
- the stretch wrap is pinched within a nip defined by the outermost windings of the cable wound on the spool and the free end of the cable.
- the pulling clamp is further configured for and operable for moving downwardly relative to the spool of wound cable so as to dispose the stretch wrap between the outermost windings of the cable wound on the spool and the free end of the cable.
- the pulling clamp is mounted on an angled rail that is movably attached to the housing with a predetermined angle such that the pulling clamp and a starting end of the stretch wrap are moved in a generally tangential direction relative to an outer periphery of the cable wound on the spool.
- the pulling clamp is further configured for and operable for releasing the starting end of the stretch wrap in contact with at least a portion of the outermost windings of the cable wound on the spool so that the stretch wrap disposed between the outermost windings of the cable and the free end of the cable is wrapped around the spool as the remaining length of the cable is wound onto the spool.
- the invention is embodied by a method for securing the free end of an elongate, flexible component wound onto a spool.
- the method includes providing a spooling machine having at least one spooling head for winding a length of the elongate, flexible component onto the spool and providing a stretch wrap applicator operably coupled with the at least one spooling head for applying stretch wrap to the elongate, flexible component wound on the spool.
- the stretch wrap applicator includes a pulling clamp and a length of the stretch wrap.
- the method further includes moving the pulling clamp from an initial position around a free end of the elongate, flexible component wound on the spool.
- the method further includes gripping a starting end of the stretch wrap with the pulling clamp.
- the method further includes moving the pulling clamp and the starting end of the stretch wrap back to the initial position with the stretch wrap disposed between the free end of the elongate, flexible component and outermost windings of the elongate, flexible component.
- the method further includes moving the pulling clamp in a downward direction so as to pinch the stretch wrap within a nip defined between the outermost windings of the elongate, flexible component and the free end of the elongate, flexible component.
- the method further includes cutting the free end of the elongate, flexible component and wrapping the stretch wrap around the outermost windings of the elongate, flexible component until the free end of the elongate, flexible component is secured by the stretch wrap.
- the spooling machine includes two spooling head and a transverse rail and the stretch wrap applicator is configured for and operable for moving in a transverse direction along the rail relative to the spooling heads.
- the stretch wrap applicator moves between a first spooling head of the spooling machine and a second spooling head of the spooling machine subsequent to securing the free end of the elongate, flexible component wound on a spool of the first spooling head.
- the pulling clamp is mounted on an angled rail that is movably attached to the housing with a predetermined angle such that the pulling clamp and a starting end of the stretch wrap are moved in a generally tangential direction relative to an outer periphery of the cable wound on the spool.

- the coil movers 62 are positioned so as to grip the coil 24, 26 as the cable 24 is cut to create a free end of the cable. If necessary, the coil 24, 26 is rotated up to about one-quarter turn to locate the free end of the cable in an optimum position.
- the coil movers 62 move the coil downwards with the coil supported by a pair of side guides 64.
- the side grippers are engaged with the coil in a suitable manner, such as by a pneumatic cylinder.
- a position sensor for example a Hall Effect sensor, may be utilized to identify that the side grippers 66 are in the correct position as they move upwards to engage the coil 24, 26.
- the movement of the side grippers 66 into engagement with the coil 24, 26 should be accomplished while the coil is being moved downwards without an additional interruption (stoppage) of the movement of the coil.
- a position sensor for example a Hall Effect sensor, may be utilized to indicate when the cable end holder 70 is in the proper position to engage the free end of the cable 24.

- the guide 68 may be disposed, for example, on the orbiter 80.
- the gripper 72 tilts downward. As a result, the starting end of the stretch wrap 40 is secured by the next layer of the stretch wrap. As shown in FIG. 20, when the starting end of the stretch wrap 40 is secured under the next layer of the stretch wrap, the gripper 72 releases the plastic stretch wrap and an air blower is used to force the free end of the cable 24 under the next layer of the stretch wrap.
- the open gripper 72 moves back upwards and the roll of stretch wrap 40 is stopped in its home position.
- the finishing end of the stretch wrap 40 is secured by the gripper 72 and the stretch wrap is cut in a suitable manner, for example by a blade, a hot knife or a hot wire driven in a suitable manner, for example by a pneumatic cylinder.

- FIG. 23 shows that the cable end holder 70 can then release the free end of the cable 24.
- An upper coil mover spade 74 is moved into position by a pneumatic cylinder to ensure that it is clear for the coil movers 62 to move upwards relative to the coil 24, 26.
- the coil 24, 26 wrapped in stretch wrap 40 is held in place by the side grippers 66 alone, which are not visible in FIG. 23.
- FIG. 24 illustrates that when a side gripper valve is operated to release the pressure of the side grippers 66 on the stretch wrapped coil 24, 26, the side grippers are not yet opened.
- the coil 24, 26 is then pushed out from between the side grippers 66 by suitable means, for example a pusher operated by a pneumatic cylinder.
- suitable means for example a pusher operated by a pneumatic cylinder.
- the stretch wrapped coil 24, 26 slides down a guide 89 onto a driven conveyor system 90, as shown in FIG. 25 and FIG. 26.

- a single stretch wrap applicator is transversely moveable on the spooling machine relative to two spooling heads so that the stretch wrap applicator is usable with both of the spooling heads.
- the stretch wrap applicator includes a pulling clamp for gripping and pulling a starting end of the stretch wrap into a nip between the outermost windings of the cable already wound onto the spool and the free end of the cable. The stretch wrap is then wrapped around the spool of wound cable and the free end of the cable is cut and secured beneath the stretch wrap.
- a stretch wrap applicator includes a pair of coil movers that position a coil of cable wound on a spool relative to the starting end of stretch wrap. The free end of the cable is secured while the stretch wrap mounted on a rotary arm is wrapped around the coil with the free end of the cable secured beneath the stretch wrap. The coil is then released and pushed onto a driven conveyor system to be delivered to a container or a pallet for storage and transport.
