Abstract

Apparatus and method to prevent the backing material from necking-in while a pile fabric is being tufted by applying a uniform and a greater tension on the backing material prior to entering the front feed rolls of the tufting machine.

Claims

1. A method to produce a tufted pile fabric on a tuftiNg machine having front feed rolls and back feed rolls comprising the steps of:

providing a supply of pile fabric backing material, supplying the fabric to the front feed rolls, tufting the backing material, supplying the tufted fabric to the back feed rolls and placing the backing material under a tension higher than the tension of the backing material between the front and back feed rolls prior to supplying the backing material to the front feed rolls.

2. The method of claim 1 wherein the backing material is positively rotated from the backing material supply roll.

3. Apparatus to produce a tufted pile fabric comprising:

a first set of rolls in geared relationship, a second set of rolls in geared relationship spaced from said first set of rolls, means to supply a backing material to and between said first and second set of rolls and means to tuft said backing material between said sets of rolls, said means to supply the backing material including a means to apply a tension to the backing material prior to contact with said first set of rolls which is higher than the tension on the backing material between said first and second set of rolls.

4. The apparatus of claim 3 wherein said means to supply backing material includes a roll means to positively rotate the backing material supply roll.
