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

[0041] 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 means 106 at one end of each of the grooves 102 against which the elongated rod 104 of the filter rests when the elongated rod 104 of the filter is received into the groove 102 The stopper is placed.

[0042] 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...

Abstract

A filter rod forming machine comprising an operating table for forming wrapped filter rods; a cutting blade for cutting said wrapped filter rods into rod segments (104); and a conveying device for conveying The apparatus comprises a drum (100) having a plurality of spaced apart grooves (102) on the outer surface of the drum for receiving the strip segments ( 104). The cartridge includes a stop (106) at one end of each of the grooves, the filter rod engaging the stop when the filter rod is received into the groove The devices are adjacent. The stop (106) includes a pin (108) having a main cylinder having a first diameter (D1) and extending along the groove (102) between a first end and a second end. ) extending along an axis (F), at said first end, said pin is attached to the frame. Said pin (108) includes an abutment portion (118) extending along said axis (F) from said second end of said main cylinder, said abutment portion (118) having a diameter smaller than said first diameter ( D1) of a second diameter (D2) and presenting a substantially planar surface for abutting the end of said elongated 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,...
