Abstract

Tubular textiles pass over a spreader (3) disposed within the textile tube (4) as they are wound into a roll. The spreader (3) in positioned by a support (7) including a slot arranged to locate the spreader member close to the surface of the roll and further arranged to facilitate passage of the textile through the slot but to prevent passage of the spreader member. The support (7) is pivotally mounted to bear on the roll being wound. <IMAGE>

Description

SPECIFICATION Tubular textile material winding apparatus This invention relates to a tubular textile material winding apparatus which may be used for winding tubular textile material onto a roll.

It is a problem with existing machines used for production of tubular textile material that the material may be stretched during delivery to a roll onto which it is wound. This may result in uneven winding onto the roll due to variation in the width of the material. Subsequent cutting of lengths of material from the roll is inaccurate since the stretched material, which may be patterned, may revert to its original dimensions after cutting.

According to the present invention a tubular textile material winding apparatus comprises a spreader member disposed in use within said textile material and a support arranged with the surface of a roll onto which said material is wound.

Preferably said support is moveable to accommodate change in size of the roll as material is wound onto it.

The support may comprise a slot having a smaller dimension than the spreader member, so that the spreader member cannot pass through the slot and become wound onto the roil.

The apparatus may further comprise an axle, bobbin or spool onto which the said roll is formed.

Preferably the support comprises a pair of rounded members forming a slot which is sufficiently narrow that the spreader member cannot pass through it. The rounded members are preferably disposed in contact with the surface of the roll so that the tubular material passes through a minimal distance between engagement with the spreader and being wound onto the roll.

Interchangeable spreader members may be provided, permitting tubular fabrics of different diameters to be wound and alternatively permitting a tubular material having a particular diameter to be wound onto rolls of different widths.

The pair of rounded members may be secured together by a mounting pivotable about an axis parallel to the axis of the roll. This ensures that both of the rounded members are always in contact with the surface of the roll during use. The said mounting is preferably pivotally secured to a support structure which is in turn pivotally secured to the frame of the apparatus thereby facilitating movement of the mounting in a direction which is generally radial of the roll to accommodate increase in size of the latter during use of the apparatus.

The rounded members may comprise rollers or may be fixed and not rotatable. Rollers are preferred for use with thicker textiles. Preferred members are constructed from low friction material such as nylon or polyethylene although other plastics materials or metal may be used.

The spreader member preferably takes the form of a generally rectangular sheet or frame having rounded edges, a dimension of the rectangle being equal to the desired width of the roll.

The spreader member may be formed from any convenient material including wood, metal or plastics materials.

The invention is now further described by way of an example with reference to the accompanying drawing: Figure 1 which illustrates apparatus in accordance with a preferred embodiment of the invention.

The apparatus shown in Figure 1 comprises an axle 1 about which a roll 2 of tubular textile material is wound. The textile material 4 may be iining material for injection moulded footwear or any other tubular textile.

The generally rectangular spreader member 3 composed of wood and having rounded edge is disposed within the tubular textile material 4 and is supported close to the surface of the roll 2 by two guides 5 which have a narrow slot between them through which the textile 4 but not the member 3 may pass. The guides 5 which comprise rollers are secured at each end to each other by supports 6 which are pivotally mounted upon linkages 7 by means of screws 8, the pivotal axis being parallel to that of the roll 2. The linkages 7 are separated by a sufficient distance to accommodate the roll 2 between them as the diameter of the roll increases. The linkages 7 are in turn pivotally mounted to a rod 9 supported by further linkages 10 secured to the apparatus, such as a knitting machine, which forms the tubular material.The linkages 7 are free to rotate about the rod 9 as the diameter of the roll 2 increases.

The pivots 8 serve to maintain the guides 5 in contact with the roll 2 as rotation about the rod 9 takes place.

Spreader members having different lateral dimensions may be interchanged with the member 3 to facilitate winding of textiles of different diameters or of textiles of the same diameter onto rolls of different widths.

1. Tubular textile material winding apparatus comprising a spreader member disposed in use within said textile material and a support arranged to locate the spreader member close to or in contact with the surface of a roll onto which said material is wound.

2. Apparatus as claimed in claim 1, wherein the support is movable in use to accommodate change in size of the roll as material is wound onto it.

3. Apparatus as claimed in claim 1 or 2, wherein the support may comprise a slot having a smaller dimension than the spreader member.

4. Apparatus as claimed in any preceding claim comprising an axle, bobbin or spool onto which said roll is formed in use of the apparatus.
