Abstract
Abstract Automatic Apparatus for forming embossed zig-zag line patterns in pile fabrics in which a pile fabric is moved in one direction and a header connected to a source of fluid under pressure and having spaced jet spray nozzles set into it is reciprocated over the fabric in a direction transverse to its line of movement. The apparatus includes mechanism for varying the length and the pitch of the lines of the design produced and also for providing a dwell at the end of each stroke of the header to produce longitudinal embossed line sections that connect the adjacent ends of the zig zag lines.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
Apparatus for forming patterns in pile fabrics comprising a stand, means on said stand for moving a pile fabric in one direction at a constant rate of speed, a header having a plurality of spaced spray nozzles set thereinto and in proximity to said pile fabric, means at one end of the stand for flexibly connecting said header to a source of fluid under pressure, means at the other end of the stand for reciprocally moving said header in a movement transverse to the direction of said fabric, means controlling the rate of movement of said header and timing means for providing a time-regulated dwell in the movement of said header for providing an embossed pattern on the pile fabric including a stroke extending in the direction of movement of said fabric.
Claim 2
Dependent Claim
132 words
Apparatus for forming patterns in pile fabrics comprising a stand, means on said stand for moving a pile fabric in one direction at a constant rate of speed, a header having a plurality of spaced spray nozzles set thereinto and in proximity to said pile fabric, means at one end of the stand for flexibly connecting said header to a source of fluid under pressure, means at the other end of the stand for reciprocally moving said header in a movement transverse to the direction of said fabric, means controlling the rate of movement of said header and timing means for providing a time-regulated dwell in the movement of said header for providing an embossed pattern on the pile fabric including a stroke extending in the direction of movement of said fabric.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 wherein said timing means includes limit means for providing said time-regulated dwell at the end of a recipro-cal movement of said header.
Claim 4
Dependent Claim
118 words
The apparatus of claim 1, wherein said means reciprocally moving said header, comprises a cylinder having a port at each end, a piston within said cylinder having a piston rod extending from one end of said cylinder, said piston connected to said header, a conduit connecting each of said ports to a source of fluid under pressure, each said conduit including a two-way valve adapted to alternately connect the connected port with said source of fluid under pressure and with atmosphere and means alternately actuating each said valve to connect the port associated therewith to said source of fluid under pressure while the other of said valves is actuated to connect the other of said ports to atmosphere.
Claim 5
Dependent Claim
21 words
The apparatus of claim 3, wherein means are provided in each said conduit for controlling the volume of fluid passing therethrough.
Claim 6
Dependent Claim
31 words
The apparatus of claim 3, wherein said means alternately actuating said valves to connect their associated ports to said source of fluid under pressure and to atmosphere includes electrical control means.
Claim 7
Dependent Claim
45 words
The apparatus of claim 5, wherein said electrical control means includes a solenoid operatively connected to each said valve for moving said valve alternately to connect the associated port to said source of fluid and to atmosphere, each said solenoid connected in an electric circuit.
Claim 8
Dependent Claim
53 words
The apparatus of claim 6, wherein said electric circuit includes a pair of spaced switches, each actuated by said piston at the end of one of its strokes, and relay means interposed in said circuit between said switches and said solenoids to maintain each said solenoid in fixed position during each piston stroke.
Claim 9
Dependent Claim
48 words
The apparatus of claim 7, wherein said timing means comprises an adjustable timing mechanism interposed in said circuit with each said relay and its connected solenoid whereby an embossed zig-zag pattern may be produced on the pile fabric, including a stroke extending in the direction of movement thereof.
Claim 10
Dependent Claim
35 words
The apparatus of claim 7, wherein means are provided for regulating the length of the reciprocating strokes of said piston whereby zig-zag patterns having strokes of varying length may be embossed on the pile fabric.
Claim 11
Dependent Claim
60 words
The apparatus of claim 9, wherein said means for regulating the length of said piston strokes comprises a pair of threaded rods and means connected to said piston inter-mediate said switches threadedly supporting said rods, each said rod arranged to contact one of said switches, said rods adapted to be adjusted to vary the distance between their switch con-tacting ends.
Claim 12
Dependent Claim
45 words
The apparatus of claim 1, wherein said means for moving a pile fabric comprises an endless conveyor belt and means mounting said conveyor belt for movement including a pair of spaced rollers, one of said rollers connected to a driving mechanism to be actuated thereby.
Claim 13
Dependent Claim
88 words
The apparatus of claim 11, wherein said spaced rollers are mounted on a frame and a third roller is mounted on said frame in close proximity to and substantially on a level with said one roller, said third roller adapted to have the fabric pass thereover and having a roughened surface adapted to frictionally engage and move said pile fabric from said belt, said third roller operatively connected to the driving mechanism of said one roller to be, thereby, rotated at the same speed as said one roller.
Claim 14
Dependent Claim
24 words
The apparatus of claim 12, wherein said roughened surface of said third roller comprises a stIffbristled cylindrical brush sleeve mounted on said third roller.
