摘要： This improved apparatus and process for manufacturing jet impingement type filters for smoking articles utilizes a normally substantially air impervious sheet material having a plurality of preformed smoke passing perforations therein and a rod of smoke pervious filter material. A tab of the perforated sheet material is positioned over the end of the rod of filter material by securing a peripheral portion of the perforated tab to the longitudinal surface of the filter rod adjacent an end whereby a major portion of the tab extends beyond the end and folding the major portion transverse the axis of the filter rod with peripheral areas extending radially outwardly from the longitudinal surface. These peripheral portions are further folded or draped over the longitudinal surface of the filter rod and secured thereto so as to form a cup-like enclosure or cap over the end. The preferred apparatus for assembling the filter comprises a female die, means for successively tabbing filter rods with the perforated sheet material and aligning the tabbed filter rods adjacent the opening in the female die with the tabs folded therebetween and means for effecting relative reciprocal movement whereby the female die cups or caps the tabs over the ends of successive filter rods. The resulting cupped-tab filter plugs are then disposed in gaseous communication with a smokable material such as a cigarette rod by, for example, an overwrap of conventional tipping paper.

摘要： This improved process and apparatus for manufacturing jet impingement type filters for smoking articles utilizes a substantially air impervious sheet material and a rod of smoke pervious filter material. A tab of the sheet material is positioned over the end of the rod of filter material with peripheral areas of the tab extending radially outwardly from the longitudinal surface of the rod. The peripheral areas are folded over the end of the rod so as to form a cup-like enclosure or cap and are secured to the surface of the rod, preferably by a heat-activatable, pressure- sensitive adhesive which is precoated on the sheet material. Smoke passing perforations are provided in the sheet material and function, in the finished combination when smoked, as accelerating jets or orifices for the smoke which impinges on the pervious filter material. The preferred apparatus for assembling the filter comprises a female die, means for successively aligning filter rods adjacent the opening therein with tabs of the sheet material therebetween and means for effecting relative reciprocal movement whereby the female die caps the tabs over the filter ends. The resulting filter plug is then disposed in gaseous communication with a smokable material such as a cigarette rod by, for example, and overwrap of conventional tipping paper.
