Problems solved by technology

However, this may have the undesirable effect that excess adhesive accumulates on the surface of the transfer cylinder that receives the wrapped filter rod portion when leaving the wrapping station
For this reason, the filter rod forming machine may have to be stopped frequently, thus undesirably increasing machine downtime

Embodiment Construction

[0042] figure 1 Details of the delivery means of the device according to the invention are described. The transfer device includes a drum 100 having a plurality of spaced grooves 102 on the outer surface of the drum 100 . The groove 102 is constructed and arranged to receive the elongated strand 104 as the drum 100 rotates. The cartridge 100 further comprises a stop 106 at one end of each of the grooves 102 against which the elongated filter rod segment 104 rests when the elongated filter rod segment 104 is received into the groove 102. Stop device placement.

[0043] if still image 3 In more detail, the stop device 106 includes a pin 108 having a main cylinder 110 having a first diameter D1 of about 8 mm and a first end 112 and a second end opposite to the first end 112 114 extending along the axis (F) of the groove, at said first end the pin is attached to a cartridge frame 116 mounted on the cartridge 100 (see figure 2 ). Furthermore, pin 108 includes an abutment po...

Abstract

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 flatsurface for abutting an end of the elongate filter rod.

Description

technical field [0001] The present invention relates to an apparatus for manufacturing filter rods used in the manufacture of smoking articles such as filter cigarettes. Background technique [0002] Filter cigarettes typically comprise a tobacco cut filler rod surrounded by a wrapper and a cylindrical filter aligned in end-to-end relationship with the wrapped tobacco rod and attached thereto by tipping paper. Filters generally consist of one or more mouthpieces of fibrous filter material. A suitable fibrous filter material is cellulose acetate tow, usually treated with a plasticizer like triacetin. One or more mouthpieces are surrounded by a paper material commonly referred to as a "mouthpiece wrap". [0003] Manufacturing filter rods from continuous fiber filter tow includes moving the filter tow in a generally longitudinal direction through successive processing steps to align the fibers of the tow; collecting, compressing and forming the tow into a predetermined shape,...
