A cutting head (26) is provided also with a notching blade (30) to enable it to cut a length shorter than the blade width of a round blade (27). In order to eliminate the need for compressed air supplying equipment and simplify the mechanism thereby to make it compact and light weight, an angular displacement servo motor (16) is used as a common drive source for causing angular displacement of the round blade (27) and angular displacement of the notching blade (30). A cam motor (17) causes a round blade cam (37) and a notching blade cam (38) to make angular displacement thereby to selectively cause the round blade (27) and the notching blade (30) to work on sheet material (2) placed on a cutting table (3) an cut it.

An image giving a feeling like the feeling of an actually knitted fabric knitted with a knitting yarn is displayed. Linear knitting yarn image data (1) is divided with a mesh (2). The mesh (2) is made to match a deformed mesh (3) deformed along the shape of a knitted loop (4). The knitting yarn image data (1) is subjected to an image drawing processing by a mesh deforming technique to create the image of the knitted loop (4). A lower section (4a) and an upper section (4b) are defined in the portion where knitted loops (4) are superposed, combined as a knitted fabric (6), and displayed. Fuzz is also reproduced, and consequently the feeling like that of an actual knitted fabric can be given.
摘要:
A knitting support system for a knitted product, comprising a knitting machine-use adjustment data storing means (28) for storing knitting machine-use adjustment data for many knitted fabrics, a retrieved information storing means (22) for storing various parameters of knitted fabrics as retrieval information used for retrieving knitted fabrics, similar to a knitted product to be knitted, from stored knitting machine-used adjustment data, a retrieving means (24) for inputting as retrieval conditions the parameters of a knitted product to be knitted and retrieving similar knitted fabrics from retrieval information stored in the retrieved information storing means (22) according to the input retrieval conditions, and an output means (30) for reading for outputting the knitting machine-use adjustment data of knitted fabrics corresponding to retrieval results from the retrieving means (24) from the knitted machine-use adjustment data storing means (28).
摘要:
The invention relates to a knitting yarn switching method and a knitting yarn switching device. When knitting yarns from yarn cones (12b, 12a) are fed to yarn feeders (13b, 14a), end portions of the knitting yarn fed to the yarn feeders (14b, 13a) are held, and when knitting yarns from the yarn cones (12b, 12a) are fed to the yarn feeders (14b, 13a), end portions of the knitting yarns fed to the yarn feeders (13b, 14a) are held. The knitting yarns to be connected thus held and the yarn cones (12b, 12a) are pieced into each other, and thereafter, holding of the end portions of the knitting yarns to be connected is released, and the knitting yarns fed from the yarn cones (12b, 12a) are cut between the pieced portions of the knitting yarns to be connected and portions reaching the yarn feeders, and the end portions of the knitting yarns cut off from the yarn cones (12b, 12a) are held.
摘要:
A sinker device of a weft knitting machine, wherein a movable sinker (8) can move a tip part (8c) forward and backward relative to the mouth part thereof (2) by the swing displacement of a needle plate (5) about the recessed part (5a) thereof. A wire spring (10) energizes the movable sinker (8) so that the tip part (8c) can move forward to the mouth part (2). A stopper (20) allowing the contact portion (8e) of the tip part (8c) of the movable sinker (8) to abut thereon to restrict the swing displacement of the movable sinker (8) by the energization of the wire spring (10) is installed at the bottom part of a base (4) near the mouth part (2). The maximum pressed amount of the tip part (8c) of the movable sinker (8) is limited by the contact of the contact portion (8e) with the stopper (20). The stopper (20) is so formed that the forward and backward movement amounts thereof relative to the mouth part (2) can be adjusted by a position adjusting mechanism (21).
摘要:
The invention relates to a method and apparatus of cutting and holding a knitting yarn in a weft knitting machine, capable of holding end portions of many knitting yarns without being provided with a holding mechanism within or in a vicinity of an area for knitting a knitted fabric. A controller (10) leads to the formation of a crossing portion (8a) that is formed using a plurality of knitting needles (4) and crosses between front and back needle beds (2) and a hold portion (8b) that is formed on the knitting needles (4) on one of the needle beds (2), with a knitting yarn (8) that has been put on standby after knitting of a knitted fabric (9) is completed until the knitting yarn (8) is used for knitting of the next knitted fabric. Thus it is possible to hold the knitting yarn (8) without a special apparatus that holds the knitting yarn (8) being provided. The hold portion (8b) can be provided within or in the vicinity of an area for knitting the knitted fabric (9). Thus, the distance by which the yarn feeding member travels can be made shorter, and production efficiency can be improved. The cutter (11) travels along the needle bed (2) and cuts the knitting yarn in the crossing portion (8a), and thus knitting of the knitted fabric (9) is not hampered.
摘要:
The invention relates to a method and an apparatus for cutting and holding a warp in a weft knitting machine that can appropriately cut even a knitted fabric knitted with a warp fed from a warp insertion mechanism, and can hold the end yarn after the cutting. In a weft knitting machine (1) in which a warp (4) can be inserted, a cut target portion (14) is formed to intersect the warp (4) while reciprocating at an interval to a needle bed (6) in a longitudinal direction thereof by swing operation perpendicular to the longitudinal direction of the needle bed (6) and lapping operation parallel with the longitudinal direction by a warp insertion mechanism (2). The warp (4) in which the cut target portion (14) is formed is hooked to one or a plurality of knitting needles (7b) and held in place. The warp (4) is then cut by causing a blade (15) moving in the longitudinal direction to act on the cut target portion (14) thus held. The warp (4) existing on the warp insertion mechanism (2) side from a cutting position of the cut target portion (14) is hooked to the knitting needle (7b) and held in place. Next knitting with the warp can be started with the warp end kept held.
