Variable-density square frame beam metallic combination reed

Abstract

The invention discloses a variable-density square frame beam metallic combination reed, which is characterized in that a plurality of unit reeds in different density specifications are parallelly arranged in a square hollow casing pipe of a reed frame according to the design requirements of warp density; two ends of the casing pipe are screwed to be fixed by a bolt; each unit reed is a short reed which is demountable, and equivalent in height; two ends of the frame beam of each unit reed are flat-top ends; and the adjacent unit reeds are butted by the flat-top end. The variable-density square frame beam metallic combination reed provided by the invention is not only suitable for producing various variable-density textiles, but also suitable for balancing on-loom density textiles and off-loom density textiles; and meanwhile, a structure of the reed is easy to assemble, disassemble and reassemble, and is suitable for low-volume production of the textiles in various varieties. Compared with the traditional reed in fixed density, the variable-density square frame beam metallic combination reed provided by the invention can be well suitable for the requirements of market variations; and the unit-combined variable-density reed is simple in structure, reasonable in assembly, convenient in dismounting, and is also suitable for standardized manufacturing and production of accessories.

Description

technical field [0001] The invention relates to a textile machine accessory, in particular to a variable density combined steel reed used on a loom. Background technique [0002] For many years, whether it is a traditional shuttle loom or a new shuttleless loom, most of the reeds used are equal-density reeds, that is, the density of reed teeth on each reed is the same, so the fabrics weaved are also equal. Warp-density fabrics or fabrics with little change in warp fineness; some people have carried out certain reforms on variable-density reeds in recent years, but many of them are limited to partial changes, and have not fundamentally solved the requirements for the diversity of density changes. Due to the difference between the yarn and the running state of the loom, most fabrics have more or less warp density changes in the width direction of the finished fabric, especially at the edge of the fabric. . The variable density reed can effectively improve the problem of unev...

Problems solved by technology

The fixed form of traditional reed is not conducive to fine weaving, which seriously restricts the development of fabric varieties

Zhang Pingguo's patent (ZL Patent No. 03207963.X) claims that the invented reed can change the density of reed teeth, but only part of the variable density, and once a certain variable density reed is made, this density will be fixed on the reed and cannot be arbitrarily Changes, so that the scope of application of the fabric is restricted
