With its increased button-feeding speed and high-speed machine head capable of a maximum sewing speed of 1,800rpm the machine dramatically increases productivity. Furthermore, its button-discharging machanism and easy-to-adjust functions make it easy to change the setup when changing the buttons to be sewn, thereby eliminating wasted time at start-up.
The three different operation modes available are the automatic button feeding mode in which the machine continuously feeds the buttons in the feeder bowl, the non-feed mode in which the operator manually places the buttons in the sewing position one by one, and the small-lot sewing mode in which the operator sets the buttons in place for one garment (five or six buttons) in advance, upon which the buttons are automatically and continuously fed to the sewing position. As a result the machine can employed by a small-lot production system by selecting the appropriate operation mode.
The machine is provided with a wider sewing area to facilitate garment setting, and allows the operator to check the remaining quantity of buttons while remaining seated, thereby enhancing ease of operation. Furthermore, the machine allows the operator to continuously sew buttons with pedal depressed, thereby helping reduce the operator’s fatigue.
It comes with direct-drive electronic feed driven by a compact AC servomotor to guarantee excellent seam quality and dramatically improve flexibility and maintainability.
The machine has 55 different stitching patterns as standard. In addition to the sewing shapes, the buttonhole intervals and number of stitches can also be changed on the operation panel. The machine completely supports many different button specifications to increase its range of applicability, reduce costs associated with changes in specifications, and save the operator from having to adapt the machine to different specifications.
Custom patterns can be created on the PGM-20 and then used on the sewing machine.
The machine performs thread trimming at the optimal position by correcting the button position with respect to the needle entry of the last stitch. This shortens the thread remaining on the material after thread trimming to approx. 3.5 mm.
The machine head is a non-lubricating type. With this type, the operator never has to add oil, and staining of the sewing product with oil is an impossibility.
