PERFORMANCE
In today’s modern textile mills, where quality and cost cutting are most important, there is a great need for high volume testing. Many of today’s testing instruments do not have an automatic yarn changer, requiring an operator, which is very costly. Lawson Hemphill offers you a solution with the new Air SAK (Sample Automatic Changer).
The new SAK allows the operator to service and operate more than one machine simultaneously, saving operator costs and reducing down time of testing instruments. For example, with the 48-position rotary magazine one can preload up to 36 ends at one time. If the test duration per sample is one minute, the SAK will run continuously for 36 minutes before the operator will have to supply more yarn. The SAK provides start and stop signals to a host instrument.
The mechanics of the system include a modern programmable controller used in conjunction with pneumatic cylinders to execute the knotter and rotary magazine with rapier. This provides dependable operation with little maintenance.
