Carpet patterning machine and method

Claim 2

Method to sculpture a predetermined pattern in the surface of a pile fabric comprising the steps of: supplying a pattern to be cut into a pile fabric, supplying a pile fabric with a surface to be cut, supplying a cutting apparatus adjacent the surface of the pile fabric, tracing the pattern to be cut and in response to the tracing simultaneously moving the cutting apparatus over the pile surface to be cut and cutting the pattern in the pile surface by bending over pile fibers in the area to be cut and then releasing the bent over pile fibers individually to allow the cutting apparatus to cut a top of the pile fibers thereof against a fixed cutting blade.

Claim 3

The method of claim 1 wherein a pantograph is employed to trace the pattern to be cut and simultaneously mova the cutting apparatus to sculpture the surface of the pile fabric.

Claim 4

Apparatus to sculpture the surface of a pile fabric comprising: a template to be traced, a cutting apparatus to cut the surface of a pile fabric, said cutting apparatus having a cutting blade with a cutting axis located in a position at an angle to the surface to be cut, said cutting apparatus having a bottom portion with an opening to allow the cutting blade to project thereof, said bottom having a sloped ramp on one side of said opening and a v-shaped member fixedly attached on a side opposite side sloped ramp to interact with said cutting blade and a means to trace said template and simultaneously move said cutting apparatus to cut said pile fabric surface in the configuration traced by said means.

Claim 5

Apparatus to sculpture the surface of a pile fabric comprising: a template to be traced, a cutting apparatus to cut the surface of a pile fabric, said cutting apparatus having a cutting blade with a cutting axis located in a position at an angle to the surface to be cut, said cutting apparatus having a bottom portion with an opening to allow the cutting blade to project thereof, said bottom having a sloped ramp on one side of said opening and a v-shaped member fixedly attached on a side opposite side sloped ramp to interact with said cutting blade and a means to trace said template and simultaneously move said cutting apparatus to cut said pile fabric surface in the configuration traced by said means.

Claim 6

The apparatus of claim 3 wherein said means includes a pantograph.

Claim 7

The apparatus of claim 4 wherein said pantograph includes a first carrier operably associated with said template and a second carrier operably associated with said cutting apparatus.

Claim 8

The apparatus of claim 5 wherein said first and second carriers are rotatably mounted.

Claim 9

The apparatus of claim 6 wherein said pantograph includes a means to cause said carriers to rotate in the same direction at the same time.

Claim 10

A cutting apparatus for pile fabrics comprising: a support plate, a slot in said support plate, means mounting a double-edged milling blade cutter having teeth to said support plate with a portion of the teeth of said cutter in said slot a ramp on the bottom of said support plate operably with one end of said slot and sloping away therefrom and a fixed v-shaped cutter member located diametrically opposite to said ramp on the bottom of said support plate.

Claim 11

A cutting apparatus for pile fabrics comprising: a support plate, a slot in said support plate, means mounting a double-edged milling blade cutter having teeth to said support plate with a portion of the teeth of said cutter in said slot a ramp on the bottom of said support plate operably with one end of said slot and sloping away therefrom and a fixed v-shaped cutter member located diametrically opposite to said ramp on the bottom of said support plate.
