PINNING WASTE CONTROL SYSTEM
The cost of producing fabric is the same, whether outside of or between the stenter pins ; However, only the fabric between the pins makes money for you. The amount of fabric that ends up as saleable fabric instead of as pinning waste is traditionally controlled by the stenter operator, whose main objective is to pin the fabric close to the edge, but not close enough to risk mis-pinning. To avoid mis-pinning and the resulting fabric waste and/or machine down time, the operator may laterally position the primary edge sensor to pin deeper than necessary, thereby turning good fabric into selvedge waste.
THE TANDEMATIC PINNING WASTE CONTROL SYSTEM IS ADAPTABLE TO PRIMARY SENSOR/STENTER RAIL GUIDANCE SYSTEMS MANUFACTURED BY OTHERS.
When necessary, the operator may override the automatic mode and laterally position the primary sensor to prepare for an oncoming bad seam, torn edge or other condition which might cause a mis-pin. After the override, the primary sensor automatically returns to the position called for by the pinning waste sensor (and by management).
