There are various types of knitting machines, with Raschel and warp knitting being two major categories. Among them, the Raschel knitting machine is one of the most important machines for producing knitted fabrics. The Raschel knitting machine can be made with single or double needle bars. In the Raschel machine, the yarns from the warp beam are transformed into fabric by being looped through loops and wound onto the fabric beam. Nowadays, Raschel machines are equipped with warp-knitting devices. The Raschel knitting machine is used for lace fabric and trimming. It is also used to produce outdoor and military fabrics, and products such as backpacks.
The Raschel knitting machine uses latch needles and tongue needles or tongue pieces.
The number of needles on the Raschel knitting machine is expressed as the number of needles per two inches (5 cm). For example, a 36-needle Raschel machine has 18 needles per inch.
The chain links are typically numbered in even numbers, such as 0, 2, 4, 6, 8, with usually two links per course.
The Raschel sinker plate only serves to hold down the loops when the needles rise.
The Raschel sinker plates are not connected by a thread at the end closest to the needle bar. Therefore, they can move to the back of the machine during the remaining knitting cycle.
The edge of the needle plate is used as a fabric support frame and turning surface.
The fabric is pulled down at angles of 120 to 160 degrees by a series of draw rolls from almost parallel to the needle bar stitches.
The warp beam is located above the needle bar, with rocker shafts as the center, and the warp yarn is led down to the guide bars on both sides.
The crossbeam is placed above the machine so that fabric inspection can be done in front and mechanical inspections of the knitted elements can be done in the rear.
The guide bars begin threading from the middle bar and are machined outward from either side of the rocker shaft.
The guide bars are numbered from the front of the machine.
The Raschel knitting machine can accommodate at least four 32-inch diameter pattern heads or a large number of small diameter pattern heads.
The ease of use, simple knitting action, and powerful yet efficient lower tension make the Raschel machine particularly suitable for producing rough gauge hollow structures that are difficult to knit and fix with column-shaped needle tracks, inlay overlapping changes, and partial thread guide bars arranged with Raschel sinker plates.
Additional warps can be provided at the fabric edges to ensure that these needles knit the fabric or coils may gradually break.
