Abstract

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

Claims4

Dependent claims

A process for applying tape segments to a traveling web, comprising

providing a rotatable anvil having a peripheral surface, said anvil being supplied, interiorly with a reduced air pressure, and being provided with openings through said peripheral surface,
continuously supplying a succession of tab segments on said peripheral surface of said anvil at a first velocity while continuously rotating said anvil at a peripheral velocity at least equal to said first velocity while using said reduced air pressure to hold said segments against said peripheral surface, each of said segments being provided with an adhesive coating on a surface facing away from said anvil,
providing a continuous web of material traveling, in close proximity, but displaced from said anvil, at a second velocity which is substantially greater than said first velocity,
intermittently displacing said traveling web toward said anvil into contact with each successive tab segment while maintaining the velocity of said second web at said second velocity whereby said segments become adhered to said second traveling web.
