Problems solved by technology

[0002] Most of the pillowcases produced in the prior art adopt manual sewing technology, wherein the production process of manual sewing is: fabric cutting → upper layer fabric overlay → lower layer fabric installation lock (zipper or button) → second layer sewing, due to the existence of manual sewing technology There are many disadvantages, mainly: (1) Due to manual operation, it is difficult to standardize the processing size
(2) Manual multi-process manual operation, the product is difficult to meet the hygienic requirements
(3) Sewing technology is also prone to missing stitches, skipped stitches, broken threads, broken needles, oil stains and other phenomena that affect quality
(4) The production environment is polluted. Due to the long-term close-distance sewing, the labor intensity of the workers is high and the eyes are prone to fatigue.

Embodiment 1

[0009] Example 1: Press figure 1 In the direction of A→B→C motion trajectory, the fabric is released from the discharge shaft, and the three-layer fabrics 1, 2 and 3 of unequal width are formed after folding, and the three-layer fabric is perpendicular to the plane in the AA'BB' area. Four-side butt welding, in CC', the symmetrical center line AA'BB' is cut on the weld seam, and the standard size pillowcase can be automatically and continuously produced by the circular mechanical action of fabric butt welding→weld seam cutting.

Embodiment 2

[0010] Example 2: Press figure 2 In the direction of A→B→C motion trajectory, three layers of unequal width fabrics 1, 2 and 3 are released from the three feeding axes synchronously, and the three layers of fabrics are welded perpendicular to the plane in the AA'BB' area. In CC', the symmetrical center line AA'BB' of the weld is cut, and the circular mechanical action of fabric butt welding→weld cutting can automatically and continuously produce pillowcases of standard size (see image 3 ).

Abstract

The present invention is new making process of pillow case and relates to bedding production. Fabric with over 50 % chemical fiber content is made into pillow case via a welding process. Thus produced pillow case may be packed automatically, and the present invention can lower production cost, improve worker's production environment, lower worker's labor strength and produce product reaching the sanitary requirement.

Description

technical field [0001] The invention relates to a new technology for producing bedding, in particular to a new technology for processing pillowcases. Background technique [0002] Most of the pillowcases produced in the prior art adopt manual sewing technology, wherein the production process of manual sewing is: fabric cutting → upper layer fabric overlay → lower layer fabric installation lock (zipper or button) → second layer sewing, due to the existence of manual sewing technology There are many disadvantages, mainly: (1) Due to manual operation, it is difficult to standardize the processing size. (2) The manual operation of multiple processes makes it difficult for the product to meet the hygienic requirements. (3) Sewing technology is also prone to quality-affecting phenomena such as missed stitches, skipped stitches, broken threads, broken needles, and oil stains. (4) The production environment is polluted. Due to long-term close-distance sewing, the labor intensity o...
