Holding bars for under floor heating tubes and method and apparatus for manufacturing the bars

摘要

The method involves pressing heated plastic plastics material in a mould to form a long plastics profile (3) with a base pla (3a) and two perpendicular spaced holder plates (3b,c). At least one punching device (4) with a transversely moving cutting tool and a support (6) are provided. Aligned recesses to hold the pipe are punched in the holder plates after the rail has been extru The cutting tool projects between the holder plates and extends as far as the base plate, and shears off and ejects lengths cut rail. Independent claims are included for a device for implementing the method and for a holder rail manufactured using the method.
