Abstract

An apparatus for producing a wound cable pack having uniform pitch and inporating a twist per turn in a cable. A drum is constrained to rotational movement around an axis of rotation. A non-rotating spool, sized to fit within the drum and having a central longitudinal axis coaxial with the drum's axis of rotation, is constrained to linear movement along the axis of rotation within the drum. A cable feeding assembly is mounted to the drum for rotation therewith. The cable feeding assembly leads the cable over one end of the spool prior to being fed onto the spool from a feed point. In this way, a twist is induced in the cable as the cable feeding assembly orbits about the spool. An electromechanical system is operatively connected to the drum and the spool to synchronize the rotational movement of the drum with the linear movement of the spool.

Dependent claims

An apparatus for producing a wound cable pack having a uniform pitch and incorporating a twist per turn in a cable, comprising:

a drum having an axis of rotation, said dram being constrained to rotational movement around said axis of rotation;
a non-rotating spool sized to fit within said drum and having a central longitudinal axis coaxial with said drum's axis of rotation, said spool being constrained to linear movement along said axis of rotation within said drum;
a cable feeding assembly mounted to said drum for rotation therewith, said cable feeding assembly leading said cable onto said spool from a feed point such that a twist is induced in said cable as said cable feeding assembly orbits about said spool;
a drive mechanism operatively connected to said drum and said spool for rotating said drum and, in synchronism therewith, for imparting said linear movement to said spool, wherein said twist per turn is induced in said cable for each rotation of said drum, and wherein said uniform pitch is determined by the amount of said linear movement for each rotation of said drum;
said drive mechanism comprising:
a linear traversing mechanism operatively connected to said spool;
a drive shaft operatively connected to said linear traversing mechanism and to said drum, wherein rotation of said drive shaft causes said rotational movement of said drum and said linear movement of said spool;
and
a motor operatively connected to said drive shaft for rotating said drive shaft.

An apparatus for producing a wound cable pack having uniform pitch and incorporating a twist per turn in a cable, comprising:

a frame;
a drum having a hollow shaft attached thereto and extending therefrom along a common axis of rotation, said hollow shaft being mounted to said frame to allow rotation about said axis of rotation, wherein said drum is constrained to rotational movement around said axis of rotation;
a non-rotating spool sized to fit within said drum and having a central longitudinal axis coaxial with said axis of rotation, said spool being constrained to linear movement along said axis of rotation within said drum;
a cable feeding assembly mourned to said drum for rotation therewith;
cable routing means for guiding said cable from a pick-up point outside said frame through said hollow shaft to said cable feeding assembly;
said cable feeding assembly leading said cable over an end of said spool onto said spool from a feed point, said cable feeding assembly imparting an approximate 90.degree. turn in said cable at said feed point such that a twist is induced in said cable as said cable feeding assembly orbits about said spool;
a linear traversing mechanism mounted to said frame and operatively connected to said spool;
a drive shaft operatively connected to said linear traversing mechanism and to said hollow shaft, wherein rotation of said drive shaft causes said rotational movement of said dram and, in synchronism therewith, imparts said linear movement to said spool via said linear traversing mechanism;
and
a motor operatively connected to said drive shaft for rotating said drive shaft.

An apparatus for producing a wound cable pack having uniform pitch and incorporating a twist per turn in a cable, comprising:

a frame;
a guide pole attached to said frame for guiding said cable therealong;
a drum having a hollow shaft attached thereto and extending therefrom along a common axis of rotation, said hollow shaft being mounted to said frame to allow rotation about said axis of rotation, wherein said drum is constrained to rotational movement around said axis of rotation;

said cable feeding assembly leading said cable over an end of said spool onto said spool from a feed point, said cable feeding assembly imparting an approximate 90.degree. turn in said cable at said feed point such that a twist is induced in said cable as said cable feeding assembly orbits about said spool;
a linear traversing mechanism mounted to said frame and operatively connected to said spool, said linear traversing mechanism including means for causing said spool to reciprocate as said cable reaches either end of said spool, wherein said cable is wound in layers on said spool;
a drive shaft operatively connected to said linear traversing mechanism and to said hollow shaft of said drum, wherein rotation of said drive shaft causes said rotational movement of said drum and, in synchronism therewith, imparts said linear movement to said spool via said linear traversing mechanism;
and
a motor operatively connected to said drive shaft for rotating said drive shaft.
