  • the pile warp 15 is controlled in its relation to the pile wire tilting and the shuttle movement by a pile heddle 58.
  • the pile heddle 58 has an upper eye 59 for connection by an actuating cord 60 to a Jacquard mechanism 61 which can have cards of well known type and actuation in a well known manner providing a program to give the desired pattern effect of the pile warp 15.
  • the pile heddle 58 preferably consists of a pair of parallel flat side strips 62, having a Weight or lingo 63 connected to their lower ends to urge the heddle 58 downwardly unless it is raised by. its cord 60.
  • the pile heddle 58 between the side strips 62 has a needle strip 64 extending downwardly from the connecting eye 59 with a needle eye 65 at its lower end through which the pile warp 15. extends.
  • the pile wire 24 extends through the heddle 58 between the side strips 62 so that upon tilting thereof by the cross bar 31 the needle eye 65 carries the pile warp 15 down one side or down the other of the pile wire 24 to form the pile loop over the pile wire 24 as desired.
  • harness frames 16 and 17 are alternately raised and lowered in the usual manner to form successive sheds for the insertion of the respective picks of the filling threads 21 to form the ground fabric.
  • the cam 46 is effective for actuating the comb 35 by the cable 39, and against the force of the spring 37.
  • the movement of the comb 35 with respect to the stationary comb 32 is effective for tilting the controlbar 31 in a direction as determined by the high portions and low portions of the cam 46.
  • FIGS. 4, 5 and 6 The effect of the tilting is shown in FIGS. 4, 5 and 6.
  • the pile wire 24 is shown as tilted to the left in FIG. 5, to the right in FIG. 6, and with the pile heddle 58 lowered in FIG. 4 to place the pile warp on the selected side.
  • the Jacquard mechanism 61 controls the cord 69 to determine the position of the pile heddle 58 and of the pile warp .15 carried in the needle eye 65.
  • the continuing movement of the loom causes the reed 26 to move toward back center.
  • the pile heddle control mechanism lowers the pile heddle 58 with the needle eye 65 on the right side of the pile wire to its lowest position.
  • the cam 46 moves the high portion 46B out of engagement with the cam follower roller 45 and brings the intermediate portion 46C into engagement therewith. This permits the comb to return to its intermediate position with the pile wire 24 untilted.
  • the shuttle carrying the filling yarn is thrown through the shed formed by the harness frames 16 and 17 and over the pile warp 15.
  • the pile heddle control mechanism lowers the pile heddle 58 with the needle on the left side of the pile wire 24 to its lowest position, thereby crossing from the right to the left side of the pile wire 24.
  • the shuttle is again thrown through the shed, with the harness frames 16 and 17 oppositely disposed for their former position and with the needle eye 65 down but on the opposite side of the pile wire 24.
  • the insertion of a filling pick over the pile warp 15 provides a pile loop.
  • a repetition of this action permits a pile loop to be formed for every pick.
  • the Jacquard mechanism can be actuated to maintain the pile heddle 58 raised for any odd number of picks to give a pile float as in FIG. 9A. Also, if desired, and using the cam 146, the Jacquard mechanism can control the pile heddle 58 to position the pile warp below th face of the ground fabric.
  • cam 146 is employed a different type of fabric can be made as shown in FIG. 9B, and the operation with the cam 146 will now be described.
  • the reed 20 While the comb 35 is being moved to the left to tilt the pile wire 24, and the needle eye 65 with the pile heddle 58 is being raised above the pile wire 24 by the Jacquard cord 60, the reed 20 is moving to its front center position at the fell of the cloth. When the reed 24) has reached this position and the top of the pile wire 24 has had the maximum tilt to the left imparted to it the needle eye 65 is at its maximum elevation above the pile wire 24. i
  • the pile control mechanism has been programmed tohold the needle eye 65 elevated through this pick.
  • the continuing movement of the loom causes the reed 20 to move toward back center and the cam 146 moves to bring the intermediate portion 146C into engagement with the cam follower roller- 45. This permits the comb 35 to return to its intermediate position with the pile wire 24 untilted.
  • the shuttle carrying the filling yarn is thrown through the shed formed by the harness frames and beneath the pile warp 15.
  • the reed 20 having reached its front center position the pile heddle control mechanism which has been appropriately programmed lowers the pile heddle 58 with the needle eye 65 on the right side of the pile wire 24 to its lowest position, thereby crossing over from the left to the right side of the pile wire 24.
  • the cam 146 has moved to bring the intermediate portion 146E to the cam follower 45 to permit the comb 35 to return to its intermediate position and thereby returning the pile wire 24 to its vertical and untilted position.
  • the shuttle is again thrown through the shed with the harness frames 16 and 17 oppositely disposed from their former positions.
  • the insertion of a filling pick over the pile warp which has crossed the pile Wire 24 forms a pile loop with the pile warp 15 interwoven with the ground warp threads 11 and 12.
  • the pile heddle 58 is raised toward its highest position.
  • the pile control mechanism is programmed to hold the needle eye 65 in a high position above the pile wire 24.
  • the cam 146 is moving to bring the intermediate portion 146G into engagement with the cam follower 45, returning the comb 35 to its neutral position and the pile wire 24 to its neutral or upright position.
  • the shuttle Upon the arrival of the reed 20 at back center the shuttle is again thrown through the shed formed by the harness frames 16 and 17 in their first position, to insert a filling pick.
  • the cam 146 advances .to bring the low portion 146H into engagement with the cam follower 45 to tilt the pile wire 24 to the right.
  • the pile control mechanism controls the pile heddle 58 and causes it to be lowered on the left side of the pile wire 24.
  • the shuttle With the arrival of the reed 20 at back center and the pile needle eye 65 having reached its lowest position and on the left side of the pile wire 24, the shuttle is again thrown through the shed formed by the harness frames 16 and 17 in their second position and over the pile warp 15 thereby forming a pile loop from right to left over the pile wire.
