PREP STAR

The Prep Star assists in the preparation of the fabric prior to the seaming process.

Full fabric length weft yarns in the fabric to be joined are automatically removed, resulting in an undamaged set of warp yarns to be used in the seaming machine.

The table and framework of .90 m wide allows easy accessibility to machine components and accentuates the ease of loading and unloading fabrics from the table. The table height of 1.1 m is ergonomic for the operator. An electronic program (PLC) controls the complete automatic thread removal process.

The working speed is adjustable to different fabric requirements. The Prep Star stops automatically if the working cycle is interrupted.

All adjustments of the machine are reproducible and the data can be stored per individual fabric on a flash drive for future use.

Thread Separator

  • WIS has developed a new thread separator especially for the use on the Prep Star.
  • This thread separator operates a specially produced and rounded neddle with four different diameters.
  • The pneumatic cylinder with six different positions is totally unique.

Needle

Wedges

  • Each pair of Wedges is individually programmable to give you maximum flexibility in separating the thread from the fabric.
  • The linear movement advances automatically with the removed threads.

Transfer Gripper

  • The Transfer Gripper takes over the thread from the thread separator and moves it back in between the open take up spool. The take up spool closes and starts to move back to give the initial pull, which will start the removing process.

Take Up Spool

  • The take up spool is designed to take over the thread after the transfer gripper head has removed the thread from the thread separator. It´s servo motor supplies constant individually programmed tension for total control. A thread removal system will then dispose of the thread once the thread is completely removed from the fabric.

Field of Application

  • For single, double and triple layer forming fabrics, which have been gapped via an automatic fringing machine or used in conjunction with the WIS TSS (thread selection system) and gluing table.
