This invention relates to clothing for use on the rollers of brushing machines, to treat the surface of fabrics to form a nap thereon.

Well known brushing machines include rollers formed of natural teasels, one disadvantage of which is that, in use, they deteriorate rapidly. Another disadvantage of the natural teasels is that a very large number thereof must be examined and graded to enable a sufiicient numberof approximately similar dimensions to be selected, to equip a machine. It has been proposed to use card clothing arranged on a manually operable appliance for brushing purposes, but such clothing is not suitable for use on the rollers of a brushing machine.

The primary object of this invention is to provide clothing adapted to be satisfactorily used instead of natural teasels on the rollers of known fabric brushing machines, especially for brushing woollen fabric.

With the above object in view, the invention relates to clothing comprising wire pins of special form, secured in a strip of flexible backing material adapted to be wound on a roller or mandrel.

One important feature of the invention resides in resilient wire pins, the ends of which are formed so that they will brush fabric and form a nap without breaking the threads.

Another feature of this invention resides in the manner in which the pin are arranged in flexible strip backing material so that when the said strip is arranged on a mandrel or roller the pins assume the desired operative position.

A further feature of his invention resides in themanner in which a strip of clothing material constructed according to the invention is arranged on to a roller or mandrel, to produce an eflicient brushing roller. 7

Clothing constructed in accordance with this invention is durable and uniform and ha many other desirable features.

Clothing for use in a brushing machine according to this invention, is characterized in that each wire pin is resilient and the end part or tip thereof is offset obliquely so that when the clothing is arranged on a roller, the end of each pin will engage the surface of fabric to form a nap thereon and withdraw without breaking the threads of the fabric.

According to the preferred construction, the clothing includes a relatively narrow strip comprising a fabric base and an upper layer of rubber or the like, and wire pins formed by the limbs of approximately U-shaped members arranged in staggered succession transversely relatively to the said strip, each pin being inclined forwardly and the end of each pin being ofiset obliquely at an angle of less than the base of each U-shaped member, the limbs thereof and the off-set tips of the said limbs being in a common plane.

But in order that this invention may be understood more readily, a practical embodiment thereof will be described with reference to the accompanying drawing wherein:

Fig. 1 is a side elevation of a portion of a strip of clothing;

Fig. 2 is an end sectional elevation of th said strip;

Fig. 3 is an underside plan view showing one preferred arrangement of pins in the backing material;

Figs. 4, 5 and 6 ar side elevations illustrating three preferred shapes of pins;

Fig. 7 is a side sectional elevation of a mandrel covered with the improved clothing;

Fig. 8 is an end elevation of a covered mandrel.

The backing material comprises a base layer l v of suitable fabric such as canvas and an upper resilient layer 2 of suitable material such as rubber adhesively secured to the said base layer l. The composite backing material may be constructed in sheet or strip form, and when made in Each pin t is substantially straight and the free end part thereof is bent to form an obliquely disposed tip 5. The angle of inclination of each tip 5 is varied according to the type of fabric to be brushed, but in all cases is less than 90 relatively to the alignment of the pin 4.

Each pin 4 is angularly inclined forwardly in respect to the longitudinal plane of the strip of base material, the pins 4, the base 3, and the offset tips of each U-shaped member extending in a common plane.

A multiplicity of pins is arranged in regular pattern in a strip of backing material, the preferred arrangement being illustrated in Figs. 2 and 3 wherein the said U-shaped members are arranged in staggered succession relatively to each other.

A brushing roller employing clothing according to this invention is illustrated in Fig. 7, wherein the clothing in strip form is spirally wound on a mandrel 6 which may have an axial bore 1. Each pin is disposed so that in the completed roller it is set'to incline forwardly in respect of a radial line projected through the mandrel.

When the strip material is spirally wound on a mandrel, each resilient pin 4 inclines forwardly of a radial line, in the direction of rotation of the brushing spindle on which the completed roller is mounted, the offset tips all being inclined in the same direction at an acute angle relatively to a line extending axially through the body of said axial line.

The resilience of the pins and\tlile flexibility of the foundation in which the-pins re mounted,

obviates fatigue induced by the constant flexing of the said pins.

, In use, any suitable number of rollers is mounted in a brushing machine, in known manner. As the said rollers rotate, the benttips 5 of the pins 4 pick up the'surface fibres of the material being brushed, but because of the formation and alignment of the pins and their setting in relation to the direction of rotation of the roller, to gether with the angle at which they encounter the surface of the fabric being brushed, the said tips tend to disengage from the raised fibres, and while serving their primary purpose of forming a nap, do not break the threads of the fabric.
