Claims

[Scope of utility model registration request]

An outer cylinder having a spiral groove formed on the inner circumferential surface and an entrance for feeding out the core material at the tip thereof, and a holder guide rotatably disposed within the outer cylinder, the front end of the holder guide is provided with an opening that vertically aligns with the entrance/exit of the outer cylinder, and the rear end of the holder guide is rotatably connected to the rear end of the outer cylinder so that it can be rotated from the outside of the outer cylinder. A core material holder that grips the core material at its front end is disposed within the holder guide so as to be slidable in the vertical direction, and the holder guide has a vertical guide groove. The core holder is provided with a horizontal protrusion, and the protrusion protrudes from the guide groove and engages with the helical groove on the inner circumferential surface of the outer cylinder. Material feeding mechanism.
