Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape end connection method used in an active yarn feeder groove for keeping the tension of knitting yarn supplied to a stockinette knitting hall constant, and a processing tool therefor. , stockinette knitting machines, etc. use knitting yarn wrapped in a so-called cone shape. These cones come in various shapes and sizes, and depending on the position where the cone is installed and the usage status of each cone, each knitting thread cannot be unraveled smoothly from each cone, so stockinette knitting is difficult. It is extremely difficult to keep the tension of the knitting yarn supplied to the machine constant at all times.
It is lif. For this reason, wire yarn is used in stockinette knitting machines, etc.
Casting is a process in which the knitting yarn is forced out from each cone through an active yarn feeding mechanism and fed while maintaining a constant tension.

This bond pole yarn feeding machine tIIIv has a large number of yarn feeding pulleys arranged in a circular shape on one plane Ii:u, and connects all the pulleys with an endless tape with both ends connected to each other. In this system, the knitting yarn of each cone is fed to the knitting machine by rotating the cone and passing the knitting yarn of each cone one by one between each pulley and the tape.As the knitting yarn is crimped to the pulley by the tape, it is fed to the knitting machine as the pulley rotates. Strong: When pulled out from a ltl cone and supplied with knitted stockinette from a pulley, the tension is always constant.

The tape used in this h1 pole yarn feeder is:
This is a belt-like material made of 14 appropriate pieces of knitted fabric treated with rubber and having a predetermined length of about 1.5 + rnn in thickness and about 10 nun in width, with both ends connected in an endless manner.

Conventionally, for this connection, the opposite sides of both terminals were cut diagonally in the width direction, and a 9.7 special adhesive was applied to the cut surfaces, and they were bonded together by heating, but due to the thickness Because it is thin and hard, it takes a lot of time to cut the end of the enamel, and it takes a lot of time to heat and bond the mating surfaces together, so it takes almost an hour to make one piece of tape. It also required Furthermore, the critical point is that the adhesive strength is relatively weak and the durability is short.

Stockinette knitting machines and other knitting machines are being operated at high speeds these days, so if they are stopped for nearly an hour due to a tape failure, they will suffer a large economic loss, so spare parts are always made. If you keep it in place and have to quickly replace it when it breaks down, in that case you will need to spend extra money because the wood is relatively expensive.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to connect the ends of the tape extremely easily, and to obtain a tape with high strength and long service life at the connected point. The present invention aims to provide a method for connecting parts and a processing tool therefor.

1 and 2 showing one embodiment of the present invention will be described in detail below. ■ is with both terminals 2 on the center line C in the length direction;
This is a tape in which a locking portion 4 and a locking portion 5 are provided at positions a predetermined distance inside from the tape 3.

The locking part 4 has a rectangular through hole 7 provided on one end 6 side of the terminal 2 at a predetermined distance inward from the terminal 2 along the longitudinal center line CJ2, and It consists of a cut 8 cut on the center line C from the through hole 7 to the PJ side and having approximately the same length as the width of the tape 1. The mooring portion 5 has a square cutout on the other end 9 side where the terminal 3 is located, at a position 1 a predetermined distance inside from the terminal 3 on the center line C'2 in the longitudinal direction, from both sides in the width direction. A neck 10 having a width equal to or equal to the width of the formed Qi diary hole 7 and an appropriate length, and a terminal from the neck 10:
(It consists of 1 head part 11.

The method of connecting the ends of the tape 1 is to make the terminal 3 of the other end 9 perpendicular to the center line C of one end 86 in the width direction, and
After inserting the head 11 into the notch 8 and penetrating the anchoring part 5 into the locking part 4, pull the other end 9 from the one end 6 to connect the one end 6 and the other end 9. L' so that they overlap?
When T'If4 rfVll 0 is fitted into the tomoe through hole 7, the part 41 of the locking part 5 is locked via the head 11, and both ends 6 and 9 are connected.

The tape 1 with both ends 6 and 9 connected is used by being hung on a large number of Yarn feeding pulleys in the same way as in the conventional tape with its ends bonded under heat and pressure.

In this case, the connection of both ends 6 and 9 of the tape l is extremely simple compared to conventional heat bonding, and furthermore, the formation of the locking part 4 and the anchoring part 5 is easy as will be described later, so in case of Even if the tape breaks down, it can be replaced in a short time, saving time and cost! , T [reduced number and contributes to reduction in management costs. Moreover, for the above reasons, there is no need to always prepare spare parts, and since the method of connecting the ends is simple, it becomes possible to use parts of intermediate length that were conventionally discarded.

In addition, the mechanical strength at the point where the ends 6 and 9 of the tape 1 are connected is significantly higher than that of the conventional tape, so the useful life of the tape 1 is extended, contributing to an improvement in work efficiency.

Next, FIGS. 3 to 5 will be described in detail below, showing an embodiment of a processing tool in which the tape 11 is provided with the second part 4 and the anchoring part 5. 12 rotates the upper and lower grip handles 13 and 14 like scissors.

The jig 30 is held slidably up and down by a sliding hole 32 provided near the center of the right side surface and a screw 33 attached to the lower table 17 through the sliding hole 32. In addition, when the jig 30 is raised (Fig. 3), the upper end I with the sliding hole 32 is aligned with the insertion opening 29, and the center line C of the tape 1 is aligned with the axis of the punch 22. A recess 34 is provided at a position that matches the
The entrance of the insertion hole 29 is completely opened at the point shown by the two-dot chain line in FIG.

A method of using the above groove-forming processing tool 12 will be described in detail below. First, with the jig 30 raised up (see Figures 3 and 4), insert one end of the tape 1 from the insertion point 29 until the end hits the obstruction 1. After that, grip the upper and lower handles 13 and 14 so as to close them and lower the punch 22 until it stops at the Yuport Z5 position, then release your hands.

A spring 34 attached to the punch 22 causes the upper and lower handles 13 and 44 to return to their original positions. At step 11, an El hole 7 is bored at a position a predetermined distance inside from the end at the center line C'2 of one end of the tape 1, and the removed part of the tape 1 passes through the through hole 28. It falls into the F section.
