The application discloses an ancient wide-width weft brocade loom, which is made by removing the later additional components which are not consistent with the technical features of the Tang Dynasty from a Zru frame loom in central and western Asia as a mother model and is subjected to late periodization modification, and comprises a rack, an opening mechanism, a beating-up mechanism, a weft insertion mechanism, a warp feeding and take-up mechanism and 1-N handle jacquard devices. Compared with the prior art, the application has the advantages that the ancient wide-width weft brocade loom is systematically restored, the loom structure is designed to be consistent with the weaving technical features of the Tang Dynasty, the structure and linkage mode of each mechanism are adapted to the weaving requirements of the wide-width weft brocade, and the blank of the entity restoration of the loom is filled.

Systems, devices and methods for three-dimensional surface weaving are disclosed herein. The system includes a jacquard device, a weaving device and a roller matrix. The jacquard device configured to selectively raise or lower the warp threads to form a shed for the weft thread to travel; the weaving device configured to carry the weft thread into the shed and weave the weft thread on the warp threads; and the roller matrix with individually controlled rotate apparatus configured to control the warp threads to move forward or backward. The warp threads come from rotate apparatus installed on the roller matrix. The rotate apparatus is controlled individually to forward or reverse rotate, so that the attached warp thread is able to be longer or shorter. As the warp threads can be shortened during weaving process, the three-dimensional surface can be produced.

The invention provides an irregular through hole texture tatting vamp and a weaving method thereof, and relates to the field of spinning. The tatting vamp comprises a through hole weave and a common grain weave, the number of weave point warps of the through hole weave is two or more, the number of weave point wefts of the through hole weave is two or more, all warps and wefts of the same weave point of the through hole weave are gathered into a bundle, all wefts of the same weave point of the through hole weave are gathered into a bundle, and the common grain weave is formed. The through hole weave and the common grain weave are integrally and continuously woven; by adopting a specific weaving machine and a specific weaving method, the irregular through hole texture woven vamp is woven, all warp and weft yarns at the same texture point of the through hole texture are respectively gathered into bundles, and air holes are formed among the texture points, so that the purpose that the texture point pores can be increased without twisting the warp yarns is achieved; meanwhile, the boundary between the through hole weave and the common line weave can form an irregular curve, so that the pattern feeling is added to the fabric, the permeability of the fabric can be improved, and the problem of poor air permeability of the woven fabric is solved.

The application discloses an improved hand brocade weaving machine and a brocade weaving method thereof, and relates to the technical field of weaving machines. The machine frame comprises a front frame, a rear frame and a pattern heald support frame arranged between the front frame and the rear frame, the rear frame is provided with a warp beam, and the front frame is provided with a crimping shaft; the pattern heald support frame comprises two groups of pattern heald door frames; the pattern heald selection mechanism is arranged at the upper end of the pattern heald support frame; the pattern heald selection mechanism comprises a horizontal translation assembly, a vertical translation assembly and a lifting assembly; the horizontal translation assembly comprises two longitudinal horizontal translation vertical rods, a horizontal translation rack is arranged at the lower part of the horizontal translation vertical rod, and a driving gear and a driven gear are arranged at the front end and the rear end of the pattern heald support frame and are engaged with the horizontal translation rack.

The invention relates to the technical field of textile machinery, and discloses a double-opening loom which comprises a loom body, a double-warp-beam mechanism is installed in the bottom of the loom body, a transmission mechanism is movably connected to the outer side of the double-warp-beam mechanism, an adjusting device is installed on the outer side of the double-warp-beam mechanism, and the adjusting device is movably connected with the transmission mechanism. A control system is arranged on the outer side of the loom body. According to the double-opening loom, through the cooperative structure of upper warp beam jacquard and lower warp beam dobby, the high-complexity pattern weaving of a jacquard machine and the high-efficiency production characteristic of a dobby machine are synchronously achieved on single equipment, the limitation of single function of traditional equipment is broken through, the electric adjusting device is meshed with the gear, and real-time switching of the transmission ratio is achieved through electric control; power transmission is flexibly adjusted according to fabric pattern complexity and production efficiency requirements, the synchronous compensation device monitors and compensates position deviation of the two parts in real time, synchronous errors are controlled within an extremely small range, fabric pattern precision is effectively improved, and the defective rate is reduced.

The invention provides a weaving machine and a weaving method for weaving irregular through hole tissue woven vamps, and relates to the field of spinning. The loom structurally comprises a let-off mechanism, an opening mechanism, a weft insertion mechanism, a beating-up mechanism, a curling mechanism and a jacquard mechanism, the opening mechanism comprises a first heald lifting set and a second heald lifting set, and the first heald lifting set and the second heald lifting set are sequentially arranged in the advancing direction of weft yarn; the jacquard mechanism independently controls a metal lifting heald to independently and alternately move up and down according to the set design; according to the irregular through hole weave tatting vamp woven through the weaving machine and the weaving method, through hole weaves and common line weaves in the irregular through hole weave tatting vamp are continuously woven at a time, meanwhile, boundaries between the through hole weaves and the common line weaves can form irregular curves, the pattern feeling is added to the fabric, the permeability of the fabric can be improved, and the fabric quality is improved. Therefore, the problem that woven fabric is poor in breathability when applied to vamps is solved.

This invention provides a loom and weaving method for weaving irregularly perforated woven shoe uppers, relating to the textile field. The loom structure includes: a warp feeding mechanism, a shedding mechanism, a weft insertion mechanism, a beat-up mechanism, a crimping mechanism, and a jacquard mechanism. The shedding mechanism includes: a first heald group and a second heald group, which are arranged sequentially along the weft yarn's direction of travel. The jacquard mechanism independently controls the metal heals to move up and down alternately according to a set design. The irregularly perforated woven shoe upper woven by the loom and weaving method of this invention has its perforated structure and ordinary texture structure woven continuously in one operation. At the same time, the boundary line between the perforated structure and the ordinary texture structure can form an irregular curve, which not only adds a pattern to the fabric but also improves its breathability, thereby solving the problem of poor breathability of woven fabrics in shoe upper applications.
