SU1362699A1 - Core for winding the roving of package for spinning apparatus - Google Patents

Abstract

The invention relates to the textile industry — to the core for winding on the packages of the roving of the hardware system of the yarn, and to prevent damage to the ends of the packings during their winding on the carding machine and unwinding on the spinning machine. The core consists of bushes sequentially installed in a row, at each end of each of which the longitudinal slots are made uniformly around the circumference with the formation of longitudinal protrusions that enter the slots of the adjacent bushings. The length of the working part of the sleeve, on which the package is stirred, is less than shear, to it the length of the sleeve is the length of the projections. When wrapping the packages, the sleeves are successively mounted on a rolling pin with the placement of the projections of each sleeve in the slots of the adjacent sleeves so that the ends of each package being wound are placed at the ends of the projections of the neighboring sleeves. When removing the sleeves with the packages from the rolling pin from the packages, protrusions protrude at half of their length, which prevent the ends of the packages from contacting with the separators when they are unwound on the spinning machine. 4 il. § (L oo Oi IsD with: x with

Description

The invention relates to the textile industry and can be used on carding machines to obtain a package from a roving of the hardware system with its subsequent unwinding on spinning machines during the processing of cotton, asbestos, wool, and their mixtures with chemical fibers.

The aim of the invention is to prevent damage to the ends of the packages when they are wound on a carding machine and subsequently unwound on the spinning machine.

FIG. 1 shows a rolling pin with a package of a card winding unit; in fig. 2 - connection of the core sleeves with each other on a rolling pin; in fig. 3 - spinner of the spinning machine; in fig. 4 - the same, top view.

The core for winding the packs 1 (cuff-points) of the roar of the hardware system of the spinning system is a series of sleeves 2 installed in series, at both ends of each of which are made evenly around the circumference of the notch 3 with the formation of projections 4. The width of the projections is less than the width of the notches. The length of the working part of the sleeves on which the package is placed is less than the total length of the sleeve by the length of the projections.

When winding the rovings on the carding machine, the sleeves are mounted on the rolling pin 5 with the trunnions 6. In this case, the protrusion of one sleeve enters the slits of the others and vice versa. The sleeves put on the rolling pin are successively locked with the flange sleeve 7 and the nut 8. The rolling pin with the sleeves with their trunnions is placed on the guide brackets of the knurling drums of the dividing head of the hackling machine (not shown) and the ropes are wound on the sleeves to form the packages. The ends of the wrapped packages (kuftochek) are located approximately in the middle of the projections and slots. The length of the protrusions and slots should be at the age of

five

The maximum capacity is limited by the width of the package and the strength of the sleeve material. The strength of the protrusion should be optimal so that under the action of the compression of the winding roving there will be no pinching of the sleeves on the rolling pin with their axial shift. With a possible displacement of the packings along the sleeves during their winding, they cannot extend beyond the ends of the sleeves due to the location of a portion of their protrusions under the adjacent packing.

After winding is finished, the packages with sleeves are removed from the rolling pin and installed on the roll drums 9 of the spinning machine between the dividers 10.

During the rotation of the roll drums, rolls are unwrapped from the packings, which are fed into the spinner feeding pair (not shown).

When unwinding the roving, the abrasion of the ends of the packings and the roving is excluded due to the fact that the sleeves will protrude approximately half the length of the projections beyond the end of the package. The contact of the roving with the separators during rotation of the packings will not occur, since friction will take place 5 between the protrusions of the sleeves and the separators.
