Abstract: The present invention provides a weaving system for woven fabrics of various kinds in small lots, capable of weaving woven fabrics of various kinds in small lots in a continuous operation by an existing weaving machine while preventing generation of waste to the minimum degree. A weaving system for woven fabrics of various kinds in small lots, comprises the steps of successively selecting a plurality of kinds of threads according to a preliminarily designed design pattern, producing a thread supplying package for the warp by jointing per a predetermined thread supply amount, warping a plurality of the thread supplying packages for the warp so as to provide a warp beam, and organizing a weft to the warp supplied from the warp beam for forming different design patterns of a plurality of kinds continuously each with a warp thread jointing area disposed therebetween in the weaving direction.

Abstract: There is provided a sample warper which comprises a warper drum, a plurality of conveyor belt, conveyor belt feed means, a plurality of yarn introduction means, a plurality of yarn selection means, a plurality of shedding means, and creel means for supporting a plurality of bobbins, wherein the feed rate of the conveyor belt can be changed in accordance with the number of yarns to be warped simultaneously on the basis of preset warping conditions and warping designs. Accordingly, undulation can be prevented from occurring on a surface of wound yarns due to change in the number of the yarns to be warped simultaneously.

Abstract: Provided are a sample warper and a warping method where data regarding yarn diameters of counts are preliminarily input and stored, counts of warping yarns as well as pattern data for warping are input, a conveyor belt feed pitch per revolution of a yarn introduction means is calculated with a warping width, the number of warping yarns, and a warping length (the number of warping windings), and the conveyor belt feed pitch per revolution of the yarn introduction means is controlled according to the counts (yarn thicknesses or yarn diameters). Accordingly, a surface of the yarns wound on a warper drum is finished in a flat state without undulation irrespective of the counts, thereby solving troubles in the next weaving step.

Abstract: A weaving system is provided to automatically maintain a printed pattern in alignment with a woven pattern as a fabric is being formed. The printed pattern is printed onto the warp yarns. A controller is used to monitor the position of the printed pattern during the weaving process relative to the position of a woven pattern that is being formed into the fabric. Should the printed pattern and woven pattern fall out of alignment, the controller then alters the longitudinal size of the woven pattern, the printed pattern, or both patterns, in order to realign the patterns.

Abstract: An electronically controlled sample warper having a yarn exchange mechanism is provided which is capable of extremely reducing yarn looseness possibly occurring during yarn exchange as compared with conventional methods, preventing large variations in yarn tension produced when a yarn is removed to improve the quality of warping and significantly improve the speed of yarn exchange, unlike conventional methods which do produce variations in yarn tension during yarn exchange to cause a degraded quality of warping, and eliminating the need for reducing a warping speed even during yarn exchange to largely reduce a warping time, as compared with the case where a conventional yarn exchange mechanism is used.

Abstract: An electronically controlled sample warper includes a yarn introduction member movably mounted on a distal end of a yarn introduction lever rotatably provided on a side surface of a warper drum for winding a yarn on the warper drum, and a plurality of yarn selection guides disposed, in correspondence with the yarn introduction member, on an end portion of a base on which the warper drum is supported. Each of the yarn selection guides is movable angularly about the base between a yarn exchange position in which it projects from the base for changing the yarn to another yarn, and a standby position in which it is retracted in the base for storing the yarn in the base. The yarn introduction member and each of the yarn selection guides are cooperative to undertake delivery of a yarn between them so as to wind yarns on the warper drum in the preset order with automatic yarn change.

Abstract: An electronically controlled sample warper capable of warping yarns on a warper drum, with windings of the yarns neatly layered one above another in regular order, thus enabling the yarns to be readily rewound on beams on a weaving machine even when the warping length, i.e., the number of multi-windings is relatively large such as four or more windings. The sample warper includes a guide operable to ensure that the yarn for the "n"th winding is wound on the warper drum such that at the beginning of the "n"th winding, the yarn is placed ahead of an end of a winding of yarn formed on warper drum by the "n-1"th winding.

Abstract: A device for joining a large number of threads on a single frame. Each of a plurality of thread clamps has a guide tube communicating with a vacuum duct. A carriage for carrying a thread joining system is arranged on the frame. As the carriage moves along the frame to a selected position a thread clamp is released and the released thread is moved by a pivot threading arm to the joining system.

Abstract: An apparatus for producing pattern warps on a cone warping machine comprises a drum, a support, a warping reed and lease rods, means for displacing the lease rods, and a driving means for rotating the drum. There is provided a tong-type gripper (60) for shifting the lease rods (61) axially and in height. The warping reed (25) is displaceably supported as a sliding reed from one central position to both sides, and it may be adjusted vertically with respect to drum (2).

Abstract: A method is provided for forming a warp beam with warp yarns having a temporary coloration to permit ready visual identification of the warp yarns during subsequent handling of the warp beam. The temporary coloration is accomplished by applying a foamed fugitive tint to the warp yarns in their path of travel from a supply creel to a winder with their speed of travel being such that the yarns are dried without having to apply external heat.

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: A fabric winding process and apparatus for preparing a fabric pattern. A winding machine comprises a rotary drive mechanism for intermittent rotation of two card-holding chucks, and a thread-guide carriage which is translatable along a path adjacent a card held by the chucks parallel to the axis of rotation of the card. The drive mechanism and carriage are coupled such that when the winding card is not rotating, the carriage shifts a distance corresponding to a selected number of turns on the winding card such that a yarn of a selected color is wound about the card at all points on the card corresponding to the color in the desired fabric pattern. In this way, a desired pattern may be prepared without the necessity of threading or knotting several yarns together.

Abstract: A method for the production of a patterned fabric comprising producing a design pattern, elongating the design pattern in length in proportion to the length of the pile warp yarn to the length of the ground warp yarn, engraving the elongated design onto printing rollers or rotary screens and printing the design onto the pile warp yarn, and winding the printed warp onto a warp beam, transferring the printed pile warp beam to a terry loom and weaving a terry fabric with the length of the pile warp yarn in a predetermined ratio to the length of the ground warp yarn to form the pile.
