Description

The invention relates to a knit machine industry, namely to the designs of the foundations of hall machines for producing a knitted fabric with areas including elastomeric yarns.

The purpose of the invention is to provide the possibility of supplying highly elastic spandex yarns directly from cylindrical packages.

Figure 1 shows the proposed device, front view; Fig. 2 shows means for placing packages.

The device mounted on the 4-comb base of the Coquette-Au machine for the undercover of coupons contains a rotation mechanism (not shown) of the shaft 2 on the third comb, a rock 3 and means for accommodating cylindrical packages 4 with a highly elastic thread. 5 of the spandex type, made in the form of a bar 6 mounted on the frame 1 parallel to the shaft 2 and along its length, To the beam 6, the arms 7 and 8 are hinged and pairwise, carrying freely rotating by bearings (not shown) on the axis 9 cups 10 for dressing packages 4 are on them. The cups 10 are located on both sides of the shaft 2 around the vertical axis 11. Each pair of levers 7 and 8 has a tension spring 12, which ensures frictional contact of the packings 4 with the shaft 2. Threading wires 1 4 and 1 5 are located under the shaft 2 under the shaft 2 for wiring the threads 5 to the eye needles 13

Depending on the web produced, the machine allows to install up to twenty pairs of packages with spandex without any additional modernization

The device works as follows.

When the machine is started up, the rotation of the shaft 2 is guided through its rotation mechanism. The cylindrical packs 4, mounted on freely rotating cups 10 and contacting the shaft 2 on both sides relative to its vertical axis 11, begin to rotate at the same linear velocity as the shaft 2 on the side, and forcibly wind and feed the threads 5 through the thread-conducting materials.

eyes 15 and 14, enveloping Scalo 3 to the needle-shaped needles of zone 13 in the zone.

As the diameter of the package 4 decreases, when the spanrex is unwound, the levers 7 and 8 carrying the package 4, under the action of the extension spring 12, and the mass of the packages 4 begin to shift towards the shaft 2 of the side, thereby ensuring a constant frictional contact of the packages 4 s shaft 2 and a uniform filing thread 3 spandex in the zone in the indigo, |

The amount of spandex feed depends on the speed of rotation of shaft 2, which can be adjusted by replacing gears in the gearbox of the machine. Adjustment of the value is necessary
