<p>This invention provides a method and apparatus for applying tape tabs (12) to a traveling web (10), for example, for placement of fastening tabs on a running web of disposable diapers. The invention provides a cutting roll (32) positioned to cut segments from a continuous infeeding web (16) of tape material against a rotating anvil (14). The anvil (14), which is traveling at a speed equal to or very close to that of the infeeding tape web (16), carries the tape segments (12) to a point on its tangency where a higher-speed traveling diaper web (10) most nearly approaches, at which point the traveling diaper web (10) is displaced slightly toward the anvil (14) by means of a protuberance (36) acting against the web. This movement causes it to come into contact with the next available tape segment (12), which becomes adhered to the higher-speed traveling web (10). This process provides for operation at higher speeds, higher efficiencies, greater flexibility and lower noise levels than previous processes. <IMAGE></p> |
