2 Claims. (Cl.-91-51) This invention relates to apparatus for finishover the platen, orifices II being provided for ing fabric. It is particularly applicable to fabric that purpose. that consists of a ground and raised pattern or Associated with this mechanism is a rotatable figure forming portions that are engaged with brush I2, which consists of a cylinder having 5 the ground and extend from one side, the obverse barbs I3 extending from its peripheral face, 5 side, thereof. which are adapted to engage the raised pattern or As an example of such a fabric there is at the figure forming portions of the fabric and operate present time on the market a marquisette which above a platen I4, which I have shown as ytrianconsists of a ground and with which rovings or guiar in form, and over the apex of which the l yarn are engaged and extend from the obverse fabric passes. These barbs I3 may be of any l0 side of the ground to form a dotted fabric which suitable material, but I have found a curved steel has become known in the trade as fluffy dot wire to be admirably adapted for the purpose. fabric.

In operation the fabricywith the pattern or figure forming portions extending from the obverse side thereof, is moved longitudinally from a supply ZIE by the tenter frame 6 or by any other means. As the fabric passes over the roller I with the reverse side of the fabric in contact with the peripheral face of the roller, the roller is rotated either in the direction indicated on the drawing by the arrow, or, if desired, in the opposite direction. When rotated ,in the direction indicated by the arrow as the grooves I9 are submerged in the liquid finishing material, the material fills the grooves and coats the applicator surfaces I8. As the grooves move upwardly above the surface of the liquid finishing material, the liquid is spilled out of the grooves over the applicator surfaces I8, so that there is a continuous supply of the liquid finishing material to the applicator surfaces I8, and the amount of this supply may be governed by any suitable means, such as, for instance, the fillers 20.

As the fabric continues to move beyond the applicator roller I, it enters the drying zone 5, where the finishing material is dried. The relationship between the speed of travel of the fabric, the amount of liquid finishing material applied to a unit area of the fabric, and the time intervening between the application of the finishing material to the fabric and its entrance into the drying zone is such that the penetration of the liquid finishing material into the fabric will be confined to the ground of the fabric or to the -ground and whatever portion of the raised pattern or figure forming portions is desired. The result of this of course is that the ground fabric is given the desired hand while the original condition of the raised pattern or figure forming portions is not substantially changed.

As the fabric passes through the drying zone the pa'ttern or figure forming portions are subjected to a blast of fluid under pressure which fiuffs the pattern or figure forming portions and gives them a fiuffy or fuzzy appearance.

'I'his fiuffing of the pattern or figure forming portions may be enhanced by the engagement of a brush such as I'I with said portions, and also by the operation of the rotary brush I2, the barbs of which engage the raised pattern or figure produce a fabric that has forming portions, separating them and flufllng them up.

These brushes I1 and I2 may operate upon the fabric either before or after the application of the finishing material to the fabric. Both may operate before the application of the nishing material, or both may operate after the application of the finishing material. n the other hand, either may operate before the application of the finishing material, while the other operates after the application of the finishing material. Either or both of these brushes may operate in conjunction with the fluid pressure fiufer II or the fluid pressure fluffer may be dispensed with.

What I claim is:

1. In a machine for finishing fabric which includes a ground and raised pattern or figure forming portions' on the obverse side thereof, to produce a fabric that has a finished ground and unfinished pattern or figure forming portions, an applicator roller having grooves extending generally longitudinally in the face thereof and adapted to carry liquid finishing material, means for rotating said roller, means for drawing the fabric over said roller with the reverse side of the fabric in position to receive the liquid finishing material from said grooves, means carried by the roller for reducing the size of the grooves, and means for supplying the grooves with liquid finishing material.

2, In a machine for finishing fabric which includes a ground and raised pattern or figure forming portions on the obverse side thereof, to a finished ground and unfinished pattern or figure forming portions,

Aan applicator roller having grooves extending generally longitudinally in the face thereof and adapted to carry liquid finishing material, means for rotating said roller, means for drawing the fabric over said roller with the reverse side of the fabric in position to receive the liquid finishing material from said grooves, means for varying the capacityof the grooves, said means for varying the capacity of the grooves including fillers removably mounted 4in said grooves, and means for supplying the material.
