In the frame of a loom, at least one of the pair of side frames has, as a reference surface, a part located in a position of the inner surface in which the heddle frame guide in a warp direction is supported and the attachment part to which at least one of the plurality of beam members is attached is formed to be an offset attachment part located on a more inner side of the frame than the reference surface.

Abstract: In order, during the processing of a thread layer, which is tensioned in tensioning means and exhibits threads running parallel to one another, to be able to vary the sequence of the processing of the threads, a storage device is proposed for the temporary deposition of at least one of the threads which can be separated from a thread layer. The storage device is provided with at least one storage means, which exhibits at least one retaining means for the retention of one or more threads under tension, whereby the minimum of one retaining means is arranged outside the plane of the thread layer. In addition, the storage device exhibits at least one transfer means, with which the thread can be transferred to the storage means.

Abstract: The invention relates to a method for thread distribution in a warping frame (1) which comprises a yarn package (2) for coiling a coil consisting of a plurality of threads (18). According to said method, a warp for producing a thread crossing or thread separation is produced, while the yarn package rotates, at the start and/or the end of a coil in a circumferential area of the yarn package (2) using warp shedding combs (40, 40a, 40b) disposed in the circumferential area of the coil (2). A partial element, especially a partial thread (49) or an auxiliary crossing rod (34, 56) is introduced into the open warp (51) while the yarn package rotates.

Abstract: For inserting a dividing cord loop into the opened shed warp on a sectional warping machine, a dividing device has at its disposal an introduction element (28) with a first, preferably movable guide arm (26) and a second, preferably stationary guide arm (27). The free ends (29, 31) of the two guide arms may preferably be led together in a pincer-like movement. The guide arms are preferably designed as tubes which in the led-together condition form a flow channel. With the help of an air conveyor (35), from a bobbin chamber (28) a dividing cord may be drawn off and as a loop be layed around a divided shed warp lying between the two guide arms and by way of a knotting means be connected to a cord loop. The connected cord loop is thereafter by way of a suction device or a blower device positioned and tensioned in a manner such that the cord loop bears at least on one side on the divided shed warp or on the warp web.

Abstract: On a sectional warping machine, the dividing-shed formation for introducing a dividing element is controlled in such a way that at least one yarn sensor (18, 18') is introduced transversely to the running direction of the shed warp (11, 12) into the opened dividing shed (15). The yarn sensor generates a control signal on detecting an incorrectly arranged yarn (34) in the feed area. The yarn sensor is preferably introduced into the dividing shed (15) together with a motor-driven element transporter (13), wherein the drive of the element transporter can be switched off and/or reversed by the control signal.

Abstract: During sizing division, a rod grid (19) comprising lease rods (7a to 7e) is used for the formation of a shed, the rod grid being able to be raised with the aid of a lifting device (22) from a middle position into an upper operating position (O). A lower operating position (U) is limited by a mechanical stop (21), the individual lease rods being sequentially permitted to fall from the upper operating position into the lower operating position by a locking device. At the same time, a yarn shed is opened for each respective cross cord (12) insertion, the yarn shed lying in the same position for each yarn group. The opening angle .beta. of the yarn shed can, in addition, be altered within specific limits. Automation of cross cord insertion is facilitated by this type of shed formation.

Abstract: With the automatic shedding mechanism according to this invention, the warping conditions are inputted by using the program setting unit 151. When it arrives at the predetermined position, the warping drum stops rotating. The closed reed 38 is operated to from lease, into which the lease rods 88 enter so as to maintain the lease and move upward to keep the lease. Next, the lease tape driving mechanism 94 is operated to have its movable unit 98 advance, so that the lease tapes T will be let off onto the warping drum 12 to the predetermined amount. Then the lease tapes go between the lease to maintain them. The above operation will be repeated for every band for the number of times according to the total number of the warping yarns and warping width. Therefore the shedding procedure will be continuously performed without cutting the warping yarns for each band. After the warping procedure, the lease cords are passed through the holes on the heddle hooks at the leading ends of the lease tapes.

Abstract: An apparatus for processing an advancing warp sheet of yarns is disclosed, and which includes at least one yarn guide reed which serves to maintain a predetermined lateral separation between the individual yarns of the warp sheet. The reed includes a transverse row of pins which define yarn receiving slots therebetween. To facilitate the thread-up of the warp sheet onto the reed, there is provided an elongate support rail which is positioned parallel to and above the row of pins. During the threading procedure, a first portion of the yarns is withdrawn from their packages and transported along the path of travel of the warp sheet through the apparatus. At each reed, the portion of yarns is laid across the upper surface of the support rail, and the yarns are subsequently transferred from the upper surface of the support rail into individual ones of the yarn receiving slots defined between the pins.

Abstract: The ends of warp yarns in a sheet form are treated at the end of a sizing process in preparation for a subsequent rewinding process. In the sizing process, the warp yarns are threaded through a reed with at least two warp yarns in each reed dent in vertically spaced relation. The at least two warp yarns are threaded through one dent in a reed in the rewinding process. Heretofore, it has been tedious and time-consuming to thread the warp yarns through the reeds since the warp yarns in one reed dent cannot be distinguished from those in other reed dents in the sizing process. In the rewinding process, a spacer such as a rod is inserted between vertically divided sheets of the warp yarns to prevent snarling. Since the warp yarns cannot be distinguished from reed dent to reed dent, it has been difficult to insert the spacer.

Abstract: An automatic leasing machine for a warp beam on which a warp delivered from the warp beam is grouped into separate warp sheets of different colors, and warps from a warp sheet in turn are subsequently separated from the sheet, passed through a gap between a pair of warp leasing cords which alternate positions once per one warp passing, and fixed by means of bonding tapes. The foregoing operation is repeated cyclically in a fully automatic fashion for all warps in the warp sheet in accordance with a given stripe design of the yarn dyed fancy fabric to be woven.

Abstract: An apparatus for dividing warp threads or ends by means of leases, comprising a first divider element or first divider means for separating a momentary edge thread from a sheet of warp threads or warp. The first divider element in conjunction with lease means, for instance constituted by lease cords, after separating a thread, changing its position relative to the sheet of warp threads in such a manner that all warp threads following the edge warp thread are displaced away therefrom. There is provided a second divider or separator element which is only capable of engaging a thread separated by the first divider element, possibly even a thread of a thread pair separated by the first divider element. The first divider element changes its position in a predetermined manner relative to the sheet of warp threads in dependency upon a programming device containing a program carrier.

Abstract: A weave-de-weave process in which a plurality of weft loops are fluidly injected from opposite sides and normal to a plurality of warp yarns to form a composite tape. The tape is deweaved after the warp is space dyed by splitting the interior of the tape to expose the looped ends of the weft.
