A method for manufacturing fabrics with a rib structure, in particular false boucl&eacute; fabrics is provided. On a weaving machine two series of warp threads (,); (,) are provided for weaving a respective fabric (,); (,). In successive insertion cycles, in each case, at least three weft threads (,), (,), (,) are inserted one above the other between the warp threads, so that in each case a set of weft threads (,), (,); (,), (,) running one above the other are inwoven by the warp threads (,), (,); (,), (,) of one of the other two series, and at least one weft thread (,); (,) is inwoven by the warp threads (,), (,); (,), (,) of the other series, so that two fabrics (,), (,) with a rib structure are woven simultaneously. A method for manufacturing loop pile fabrics is provided. Two fabrics (,); (,) are manufactured according to the above described method, and at least one weft thread (,) of each set of weft threads (,), (,); (,) (,) running one above the other functions as loop weft thread and is removed so that the pattern warp threads (,), (,); (,), (,) running above these sets form loops. The fabrics are manufactured according to the above mentioned methods, in particular false and true boucl&eacute; fabrics.

False and true boucl&eacute; fabrics, and a method for the production of such fabrics

A method for manufacturing a face-to-face pile fabric wherein first weft thread is provided in the top fabric and the bottom fabric adjacent to second and third weft threads located one above another. Three weft threads are inserted simultaneously. Each warp thread system, has binder warp threads, tension warp threads and pile-forming pile warp threads interlacing with a three-pick weave. In each case pile is formed on the first weft thread provided on the back of the second and the third weft thread. Binding of the dead pile warp thread is distributed over both the fabrics. Pile is formed on the third weft thread located on a back side. A pile thread that starts forming a pile or finishes forming a pile is first interlaced with a third weft thread before is starts forking the pile or before it is bound-in. Binder warp threads are provided to bind the first weft threads in a separate opening. Pile is formed on the first weft thread which is not provided on the back of the fabrics. Each warp thread system has two tension warp threads.

Method for manufacturing a face-to-face pile fabric having weft threads

A face-to-face carpet fabric is manufactured in a one shot-weave. A face-to-face pile fabric, more particularly a one shot-weave, is woven with single rapier or double rapier with weft elimination. The imposed working repeat for the pile warp ends goes over three picks. The working repeat of the backing fabric goes over a repeat different from that number of picks, preferably over four picks.

A gripper device for a weaving loom having a drive shaft, which rotates in one direction of rotation and the other direction in an alternate manner, where the gripper device has a drive gear rotatably disposed on the drive shaft. This drive gear has a tooth system which is engageable to the tooth system of an assembly, which is non-rotatably disposed on said drive shaft. The gripper device also includes a mechanism for engaging both tooth systems to transmit the rotational movement of the drive shaft to the drive gear, thus moving and withdrawing the gripper device into and from a shed between warp threads.

Method for single-spool weaving of a face-to-face fabric with bound-in dead pile which avoids color mixing at transitions from one pile thread color to another. When a color transition occurs through a pile thread bound into the bottom fabric by weft threads 1, 2, 3 and 4 before the transition (at weft thread 4) becomes active after the transition, this pile thread is successively guided to assume positions relative to the subsequent four shots 5, 6, 7 and 8 as follows: below, below, above and below, respectively. In another situation, in which the color transition occurs through a pile thread which was active before the transition (at weft thread 4) is bound in the top fabric after the transition by pile threads 5, 6, 7 and 8, this pile thread is made to assume positions relative to the previous four shots 1, 2, 3 and 4 as follows: above, below, above and above, respectively. The disclosed weaves ensure against to different colors ever occurring between two inner shots.

Single-spool weave without color mixing

A method for twin-spool manufacture of a two-shot face-to-face fabric comprising a top fabric and a bottom fabric including binder warp threads for forming the upper and lower fabrics respectively and pile warp threads bound as dead pile threads into the top fabric or into the bottom fabric for successive picks or passed as active pile threads between the top and bottom fabrics in successive picks. In successive picks there are formed alternately a shed between binder warp threads providing the top fabric and a shed between binder warp threads providing the bottom fabric with the insertion of two weft threads, one above the other, in each of said sheds. The two weft threads are taken to a height corresponding to the top fabric before insertion into the shed of the top fabric and then are taken to a lower height corresponding to the bottom fabric before insertion into the shed corresponding to the bottom fabric. A corresponding weaving loom enables the two weft insertion devices supported one above the other to move up and down together to carry out the method.

Method and weaving looms for manufacture of face to face fabric

In weaving face-to-face pile fabrics, in a 2-shot weave, pattern forming portions of pile warps go over 3 wefts while bound-in portions go over only 2 picks. Working pattern repeats--over 3 wefts--are defined for each possible pile warp by aprons which determine the positions of the pile warps. Resultant pile fabrics have precise pattern definition with no crossed piles at pattern borders.

A lifter mechanism for a Jacquard machine is connected to two hooks. This mechanism has one lifter element with two rollers and one roller element. This mechanism also has one lifter cord passing around under the top roller of the lifter element and is fixed by each end to one of the hooks while the roller element is immovably fixed below the lifter element. The mechanism has an additional lifter cord which is fixed by one end next to the other lifter cord to one of the hooks. This lifter cord is passed around under the roller of the roller element, around over the bottom roller of the lifter element, and is extended back down, where it connected to the warp threads. The rollers are placed on shafts, which, in a horizontal plane, form an angle (.alpha.) relative to a line parallel to the direction of the knives. The roller of the roller element is placed on a shaft which, in a horizontal plane along the other side, forms an angle (.beta.) relative to a line parallel to the direction of the knives, while the outsides of the flank pieces and of the side plates are situated in vertical planes lying at right angles to the direction of the knives.
