IMPROVED FILTER ROD MANUFACTURING UNIT DESIGNED FOR OPERATION WITH RIGID WRAPPING TAPE MATERIAL

摘要

A filter rod maker comprises an operating station for forming a wrapped filter rod; a cutter blade for cutting the wrapped filter rod into rod segments(104); and a transfer device comprising a rotating drum (100) having a plurality of spaced apart flutes (102) on an exterior surface of the drum, the flutes for receiving the rod segments (104) as the drum rotates. The drum comprises stop means (106) at one end of each of the flutes against which the filter rods abut when they are received into the flutes. The stop means (106) comprises a pin (108) with a main cylindrical body having a first diameter (D1) and extending along an axis (F) of the flute (102) between a first end, at which the pin is attached to a frame, and a second end. The pin (108) comprises an abutting portion (118) extending along the axis (F) from the second end of the main cylindrical body, the abutting portion (118) having a second diameter (D2) smaller than the first diameter (D1) and presenting a substantially flat surface for abutting an end of the elongate filter rod.
