B A Thorne: Coilers for varying lengths
Extruders producing odd lengths of profiles or hose in coils now have a UK source of coiling equipment. Generally coiling is done manually or on a simple coiler built in-house. Uponor Group company Unicor Extrusionstechnik builds a range of coilers for this type of work, and these are now available in the UK through B A Thorne (Machinery).
The basic machines are turntable coilers from 80 to 120 cm diameter with cutting, changeover and tension-free coiling from outside to inside or vice versa. Multi-layering is possible together with interleaving of virtually any material. The process is controlled by a dancer arm which feeds a signal to a Siemens PLC. More complex equipment is available with multiple stations, automatic changeover, banding, foil wrapping, boxing and other options.
