Abstract
PURPOSE: For preventing the ingress of cutting chips in pipings, to wind up the end portion made by cutting from outside a portion between a plurality of parallel grooves cut on the outer circumferential face of pipings and bent outward.
CONSTITUTION: The aluminium drum 10 of a machine or unit is held by a hanger 18 while kept connected to the bottom section of said machine or unit, and two cut grooves 22 are cut in the outer-circumferential face of a piping by an electric saw. Next, a portion between said cut grooves 22 of said piping is cut from outside and bent outward. Said bent end portion is wound up by a winding-up jig 22, and said drum 10 is cut along said cut grooves 22. Next, the improvement of said machine or unit is completed when an extended portion 16 is inserted in and coupled with the portion between the cuts of said drum 10 while said drum 10 is hung. Since said drum 10 is cut as described above, the cutting chips generated or cutting can be avoided. Thus, the inside of said piping is not required to remove cutting chips.
