Abstract: There is provided a direct-winding sample warper comprising: a warper drum; yarn winding means mounted on a circumferential surface of the warper drum so as to be rotatable circumferentially and movable longitudinally on the warper drum; a yarn selector provided in correspondence to the yarn winding means; and a plurality of parallel shedding means extending longitudinally and parallel each other on the side of the warper drum; wherein the yarn winding means is operable to directly wind at least one yarn, which is payed out from a creel on which bobbins are supported, around the circumferential surface of the warper drum. In the direct-winding sample warper, a yarn is wound directly on a warper drum by a yarn winding means without using a conveyer belt so that various inconveniences due to the conventional conveyer belt can be entirely eliminated.

Abstract: An electronically controlled sample warper which automatically exchanges yarns and winds the yarns on a warper drum in accordance with a preset yarn order. A plurality of yarn introduction mechanisms are each rotatably mounted to a side surface of the warper drum for winding a yarn on the warper drum. A yarn introduction member is arranged at a distal end of each of the yarn introduction mechanisms for holding a yarn. A plurality of yarn selection guides are arranged in one end portion of a base for supporting the warper drum corresponding to the yarn introduction mechanisms with each yarn selection guide pivotally moved to protrude to a yarn exchange position when a yarn is exchanged and pivotally moved to retract to a standby position when a yarn is accommodated. Yarns are passed between the yarn introduction mechanisms and the yarn selection guides.

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: 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 electronically controlled sample warper capable of warping a plurality of warp yarns simultaneously. In the warper, a plurality of warp yearns can be concurrently wound on a warping drum with omitting a yarn exchanging step to eliminate any time loss for the yarn exchange, thus reducing the warping period of time.
