Description

bt-1

Mechanical backlatching device

For productivity improvement - Cutters etc.

  • Thanks to this device, the thread chain is backlatched by sewing it into the overlock seams at the start of sewing in a sleeve closing operation and other similar operations.
  • This feature prevents the threads from unraveling at the start of sewing and then eliminates the need for bartacking.
