Description

The present invention relates to a set-up method for a flat knitting machine equipped with a set-up device.

In a flat knitting machine equipped with a set-up device, when knitting a knitted fabric is started as in Patent Document 1, first, the knitting needles of the front and back needle beds are set up with knitting yarn so that the set-up portion intersects on the needle bed. After knitting, the hook of the set-up needle provided in the set-up device catches the crossing portion and pulls it down, and then the knitted fabric is knitted.

FIG. 2 shows a set-up portion according to Patent Document 1. If the hook of the set-up needle 1 does not reliably catch the crossing portion 3, subsequent knitting will be hindered. Therefore, the position of the set-up needle 1 with respect to the crossing portion 3 must be accurately adjusted, and it takes time to assemble the knitting machine. In particular, in the case of a knitting machine with a wide needle bed width or a high gauge knitting machine, more precision is required and much time is required for adjustment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its object is to eliminate the need to strictly adjust the position of the set-up needles, thereby shortening the assembly time of the knitting machine. The purpose is to provide a set-up method.

In the set-up method of the present invention, in a flat knitting machine having at least a pair of front and rear needle beds, a set-up portion formed of knitting yarns by moving up and down between the front and back needle beds is caught by hooks of the set-up needles and pulled down. In the set-up method, the knitting yarn is fed to the knitting needles of the front and back needle beds to form a zigzag set-up course, and then the knitting yarn is fed to the knitting needles of either the front or back needle bed to form the knitting. After forming at least two or more stitch courses following the set-up course, the set-up needles are raised to capture the sinker loops extending between adjacent stitches of the stitch course formed subsequent to the set-up course, thereby removing the set-up portion. I tried to pull it down.

Preferably, three stitch courses are formed following the set-up course.

Elastic yarns are preferably used as knitting yarns for set-up knitting.

In the present invention, the location to be captured by the hook of the set-up needle is a wide target such as a sinker loop extending between adjacent stitches in the stitch course following the set-up course, instead of the conventional narrow target such as the intersection of knitting yarns. Therefore, the allowable range of position adjustment of the set-up needle can be widened and the time required for the adjustment work can be shortened.

Also, even if the hook of the set-up needle fails to catch the sinker loop of the first stitch course following the set-up course, the sinker loop of the following stitch course can be caught, so that the occurrence of problems can be suppressed as much as possible. .

In addition, by using the elastic yarn, the elasticity of the elastic yarn contributes to stably lowering the knitted fabric after the set-up knitting.

FIG. 1 is a diagram showing knitting steps of a set-up method according to an embodiment. FIG. 2 is a diagram showing a state in which the knitting yarn is locked at the needle bed portion according to the conventional set-up method.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

In this embodiment, an example using a two-bed flat knitting machine will be described. The flat knitting machine has needle beds (FB, BB) on which many knitting needles are arranged and a set-up device (not shown) having set-up needles 1 below the needle beds. The arrangement pitch of the set-up needles 1 in the set-up device is coarser than the arrangement pitch of the knitting needles in the needle bed, and is provided every four knitting needles so as to face the knitting needles c, g, k, .

"S+Number" in the left column of FIG. 1 indicates the number of the knitting step. The right column shows the knitting direction and the stitch holding state on the needle bed. A black point indicates a knitting needle, a capital alphabet indicates a knitting needle provided in BB, and a small alphabet indicates a knitting needle provided in FB. A V-shape indicates a pick-up stitch, and a circle indicates a knit loop.

FIG. 1 is a diagram showing knitting steps of a set-up method performed prior to knitting a knitted fabric. First, in step 1, knitting yarn is hooked by knitting needles A, c, E, g, I, k, . The stitches formed at this time are pick-up stitches. The knitting needles c, g, and k facing the set-up needle 1 are used as the knitting needles of the FB because the sinker loops (knitting yarn portions extending between adjacent stitches) of stitch courses 7, 8, and 9, which will be described later, are set-up needles. This is because the position of 1 is the center of the sinker loop, and the left and right balance of the hooked sinker loop is good. The knitting yarn used for knitting the set-up portion may be the knitting yarn used for knitting the knitted fabric. The knitted fabric to be knitted later can be lowered more stably.

In step 2, yarn is fed to the knitting needles I, E, and A of the back needle bed to form a stitch course 7 following the set-up course 5. As shown in FIG. In subsequent steps 3 and 4, knitting similar to that in step 2 is performed to form stitch courses 8 and 9 . Knitting up to step 4 is performed with the set-up needle 1 positioned below the needle bed.

Step 5 shows the state of the stitches held on the needle bed after the knitting up to step 4 has been performed. The knitting needles c, g, and k of FB hold the pickup stitches of the set-up course 5 formed in step 1, and the knitting needles A, E, and I of the BB hold the stitches of the stitch course 9 . The knitting needles c, g, and k of the FB are in a state in which the pick-up stitches of the set-up course 5 are retained, and the stitch courses 7, 8, and 9 are formed following the set-up course 5 with the knitting needles A, E, and I of the BB. be. Therefore, the sinker loops extending between the stitches together with the stitches of the stitch courses 7 and 8 knocked over from the knitting needles are drawn toward the FB side.

Step 6 shows a state in which the hook of the set-up needle 1 advances above the needle bed and descends to catch the sinker loop of the stitch course 7 or 8 . Here, it is preferable that the set-up needle 1 is of a type composed of a needle body having an inclined surface at the upper end and a slider provided with a hook in either the front or rear direction at the upper end, as disclosed in Patent Document 1. . When the set-up needle 1 rises, the sinker loop of one of the stitch courses 7 and 8 can be guided to the hook by the inclined surface of the hook storing projection and securely caught.

In this embodiment, the hook of the set-up needle 1 catches the sinker loop extending between the adjacent stitches of the stitch course following the set-up course 5 . Therefore, the allowable range of position adjustment of the set-up needles can be widened compared to narrow targets such as crossings of knitting yarns, so that the time required for the adjustment work can be shortened.

It is also possible to knit two stitch courses 7 and 8 following the set-up course 5, but by forming the third stitch course 9, if the sinker loop of the stitch course 7 is formed on the set-up needle 1 Even if the hook fails to catch it, if the following stitch course 8 can be caught, the knitted fabric can be pulled down without any problem.

In the above-described embodiment, the stitch course following the set-up course is formed with the BB, but it may be formed with the FB instead. In addition, although a two-bed flat knitting machine is used, it can also be applied to a four-bed flat knitting machine. Also, the set-up needles have been described with an example of a set-up device provided for every four knitting needles, but the set-up needles should be positioned at the position where the sinker loop of the stitch course formed subsequent to the set-up course is located. Needless to say, knitting can be carried out even if the arrangement pitch of the set-up needles is different.
