Abstract
Apparatus to prevent the accidental cutting of the selvedge backing material of a loop pile fabric being cut by a rotating cutting apparatus. The apparatus includes a plurality of fingers which engage the selvedge to maintain it in a tensioned condition in response to an automatic control which senses the position of the selvedge of the fabric.
Claims8
Apparatus to provide a cut loop pile fabric comprising a rotor, a plurality of rows of cutting means in said rotor, means to rotate said rotor, means to supply a loop pile fabric with a selvedge thereon into contact with said rotor with the loops of the fabric in contact with said cutting means, selvedge protection means on at least one end of said rotor between each of said rows of cutting means to hold the selvedge of the fabric out of contact with said cutting means and means operably associated with the edge of the pile fabric to automatically maintain said selvedge protection means in a predetermined position relative to the fabric being supplied to said rotor.
Apparatus to provide a cut loop pile fabric comprising:
- a rotor having a shaft, a plurality of rows of cutting means in said rotor, a mounting ring connected to said rotor, a plurality of notches in said mounting ring between said rows of cutting means, a stub shaft mounted on said rotor shaft, a collar member rotatably mounted on said stub shaft, a plurality of fingers connected to said collar member and projecting through said notches in said mounting ring, means supplying a loop pile fabric with a selvedge thereon into contact with said rotor and means responsive to the position of the selvedge to slidably move said stub shaft relative to said rotor to position said fingers relative to the selvedge.
