High line sizing Machine

Programming of the Machine

The drive, temperature of cylinders and size box, tension in different zones, squeezing roll pressure and warper beam braking pressure, all are controlled through PLC and can be effectively controlled through user friendly HMI (Human Machine Interface) provided at the head stock. This can also be provided in local languages for easy of operator. Besides the push button stations, a handy is also provided with the machine which gives flexibility to the operator to operate the machine from any place along length of machine.

Direct and Indirect Heating

Size box is provided with direct heating arrangement for getting the required temperature of the size mix uniformly across the size box on all sides to ensure uniform size pick-up. Indirect heating is also provided with help of additional jacketing to ensure heating of size at bottom and avoid dilution of size solution as well as to compensate the beat loss to atmosphere. Size circulation system is provided to maintain level of size solution for uniform size pick-up.

Wet Splitting

Wet splitting is done with the help of steam heated rolls, in case of heavy qualities, to reduce hairiness as well as reduce size dropping which might take place leasing zone in sizing & on the loom.

PLEVA Automatic Size Pick-up Control

PLEVA automatic size pick-up can be opted for size box, as an optional attachment (Spelling of Pleva over the machine in the picture is PLEVA)

Beam Let-Off Device

This is provided for sectional warping beams, normally with colored yarn patterns, with pneumatic braking device on both the sides.

PLC controlled High Line Sizing Machine with multi-point drive. Perfect control of size pick-up, stretch and hairiness.

Main Features :

Optimum and uniform size pick-up
Minimum loss in elongation
Minimum hairiness
Automatic tension control in different zones through PLC (Programmable Logic Control
Automatic control of different parameters such as temperature in size box / cylinder, squeezing pressure, beam pressure & pneumatic brake at creel
Higher production with good quality
User friendly HMI (Human Machine Interface)

Comb Traverse

Comb assembly has been provided with horizontal traverse for perfect beam surface by avoiding ridges & furrows and the vertical movement helps increasing the life of comb.

Multi Motor Drive

Multi motor drive is provided, with help of PLC controlled drive, along the length of sizing machine to ensure sized warp sheet with minimum loss in elongation, and thus giving higher residual elongation for higher efficiency & good quality at Shuttleless Weaving Machines, running at high speed.

Drive of the Drying Cylinder

Sized warp sheet driving the cylinders helps in the shrinkage of warp sheet during drying, specially in case of split drying. The cylinders are also provided with temperature control arrangements in required groups.

Uniform Size Pick-up

Size Box

Main Features :

This is achieved across the warp width with the help of special Anti Deflection Squeeze rolls and along the length with proportionate squeezing pressure, controlled through PLC as per the change in machine speed (Crawl to running speed and vice-versa)

The Special design of squeezing roll surface ensures minimum hairiness as sized warp sheet does not steak to squeezing roll because of its non-stickiness. Bottom rolls with size-rock coating also helps in reducing hairiness.

Special Anti0deflection squeezing rolls for uniform pick-up across the width.
Proportionate squeeze pressure with respect to machine speed to ensure uniform size pick-up along the length of beam
Special squeeze roll surface for minimum hairiness.
Option of PLEVA automatic size pick-up control

Moisture Control

Moisture content in the sized warp sheet is maintained with the help of sensors mounted on the sized warp sheet across it’s width, at the drier exit, by regulating the machine speed through PLC.
