Goodyear - Model EWS-4C/HP
Welt Sewing Machine
This high speed, accurate welt sewing machine sews the welt to the lasted upper and insole rib with a chainstitch. Operation is easy and fast. Both awl and needle penetrate the work from the welt side. Thread tension is easily adjusted and maintained by a simple adjustment. A tight seam is ensured because the thread tension is built up evenly as the stitch is set, pulling the thread down tight to the welt at low and high speed. Both needle and awl are automatically withdrawn when the machine stops.
There are two positions on the control switch. When sewing breast to breast work the switch is set to BB. When the shoe has been sewed to a point within two inches of the finish point, the knee pad is depressed. When the foot treadle is released, the welt is automatically cut off.
At the heart of the EWS 4c HP is a unique touch screen interface where all the major controls are situated. Operator adjustment of speeds and stitch over run on cut-off are all easily adjusted.
In the designing of the EWS, the three main objects were to improve the standard of work, increase the output and reduce the operational effort. The machine is equipped with:
- Electronic variable speed motor (150 to 900 rpm)
- Pneumatic welt guide
- Electronic digital temperature read-out for the waxpot
- Programmable automatic lubricating system
- Low voltage heating
