Shima Seiki has added two new versions of its automatic spreading technology to its portfolio, machines that are designed to spread and stack knitted fabric to the required length and number of plies before cutting. The P-SPR2K features improved ergonomics by concentrating often-used switches in a single, easy-to-reach location, while other operations are performed through a display panel. In addition to knife sharpening, sensors for selvedge position, fabric slack and thickness allow for optimum fabric spreading for cutting.
Fabric loading is performed with a turndown bucket, which is now at a lower position for easier access while loading heavy bolts of fabric. Furthermore, the new fabric hold-down unit on P-SPR2K allows smooth spreading without undue stress on the knit fabric by taking into consideration the stretch characteristics of knits. PSPR2K can be linked to P-CAM automatic cutting machines (NC cutting machines), allowing spreading and cutting to be performed together as an integrated production system for improved work efficiency as well as significant savings in labour.
The P-SPR2L has similar features but also includes the new Lay-Up Unit which enables fabric to be unraveled across a belt to relieve tension for more stable cutting. Fabric loading is performed with the Auto Loader, so that heavy bolts of fabric can be placed easily. P-SPR2L can also be linked to P-CAM automatic cutting machines (NC cutting machines).
