RVR’s “HFSR-46H” Fabric preparation machine automates the selvedge sewing operation of knit fabrics prior to dyeing. It is specifically designed for converting prefixed open-width knitted fabrics into a tubular form by folding the two sides and sewing the edges. It is a fully electronic machine with inverter control. The machine is administered by a PLC and controlled by an HMI (Touching Screen).
The machine automatically performs all operations until the plaiting process and requires no operational adjustment by the user. The sewing process eliminates the problems caused by the folding lines and creases during the dyeing process.
The machine incorporates a Japanese-based Kansai stitching machine for sewing.
The machine is ergonomically designed and built
A web guide sensor is used to centre the input fabric.
A 10" inch HMI Panel is included as the interactive control system
PLC control systems are used for synchronised purposes.
All rollers are synchronised with the invertor
An auto edge alignment system is used to centre the fabric for folding.
Electronic Decurler units are used in the folding process to remove edge curls.
The relaxing plaiting function is used to relieve fabric tension.
The de-threading unit is used to pull the thread, and the tubular fabric returns to its original width.
Emergency Stop facility is provided as per Safety Norms.
