Wire winding device and wire winding method
A wire winding device includes a lock jig including a pair of tip end portions configured to approach each other or separate from each other. A control portion of the wire winding device is configured to execute: a step of winding a wire onto a winding drum; and a step of making the lock jig sandwich a pulled-out part of the wire, inserting the lock jig into a clip, and opening the tip end portions of the lock jig against biasing force of the clip to open the clip.
Electric wire processing apparatus, electric wire processing method, and electric wire holding structure
An electric wire processing apparatus includes a gripping mechanism that grips a part of an electric wire, a driving mechanism that drives the gripping mechanism, an electric wire winding mechanism that winds the electric wire, and a rotating mechanism that rotates and drives the electric wire winding mechanism. The electric wire winding mechanism includes a winding drum, an electric wire clip provided on the winding drum to hold a leading end of the electric wire, and a holding member that holds an electric wire bundle.

Drum assembly adapted to accommodate wire access lines of varying diameters
One aspect of the disclosed subject matter is seen in a wire access line drum assembly that includes a tubular drum and an insert positionable therein to accommodate wire access lines of varying diameter. The tubular drum has a first and a second end and an inner and outer surface. The insert is positionable adjacent the first end of the tubular drum and has a curved channel formed therein extending between the inner and outer surfaces of the tubular drum. The insert has a ramp substantially coinciding with the outer surface of the drum at a first end portion and extending above the outer surface of the drum at a second end portion adjacent the curved channel. The height of the ramp at the second end portion is selected to be substantially similar to the diameter of the wire access line to be stored on the drum assembly.

Textile machine for producing roving and method for starting the roving production on a corresponding textile machine
A textile machine and associate method are provided for producing a roving, wherein a consolidating means produces a roving having a protective twist from a fiber bundle. A winding device is arranged downstream of the consolidating means in a transport direction of the roving and winds the roving onto a tube driven by a tube drive. An arrangement is disposed to bring the roving leaving the consolidating means during a roving production start procedure into contact with the tube. The arrangement includes a movably mounted suction unit with a suction opening that is configured to suck up the roving during ongoing roving production. Means are provided to bring the roving running between the consolidating means and the suction opening into contact with the tube during ongoing roving production. Means are further provided to cut the roving such that a section of the roving grasped by the suction unit is conveyed away by the suction unit and a section of the roving running between the consolidating means and the tube is wound onto the tube.
YARN CARRIER TUBES
The present disclosure is directed to a reusable yarn carrier tube around which yarn may be wound at high speeds (e.g., within winding machines). The yarn carrier tube may include a pick-up groove having structural features configured to better snag yarn to initiate winding of the yarn around the cylindrical body of the yarn carrier tube. The structural features may include an adaptable snagging feature that is adaptable to many different yarn types (e.g., diameter, denier, texture, material). The structural features may include projections (e.g., teeth) with incremental narrowing therebetween in the direction opposite to the rotational winding direction. The teeth may increase in sharpness (e.g., decreasing radii of curvature) as the yarn moves further into the pick-up groove.
