| titleOfInvention | Apparatus and method for continuously forming and filling tampon sacks |
| abstract | An apparatus and method for continuously forming and filling tampon overwraps or sacks wherein a web of pouch forming material is unwound from a supply roll, passed through an adhesive printer which applies spaced apart transverse stripes of heat activatable adhesive which ultimately form end seals for the sacks, the adhesive being dried on a drying drum having raised portions which coincide with the transverse stripes of adhesive. The web proceeds to a hollow tube forming mandrel and is formed around the mandrel with the longitudinal edges of the web overlapped and sealed to form the longitudinal seam of the tubing. The formed tubing is tangentially received by a rotating turret having a plurality of pleating and sealing stations spaced about its periphery, the spacing between adjoining stations corresponding to the spacing of the transverse stripes of adhesive on the tubing. Each station has a pleater which sequentially engages and gathers the tubing and sealing jaws which engage and seal the gathered tubing in the areas of the transverse adhesive stripes to form a continuous series of sacks. As the leading end seal of each successive sack is formed, a charge of particulate absorptive material is introduced through the tubing into the sack being formed, the hollow mandrel having a funnel-like hopper into which measured increments of the absorptive material are deposited, an air jet in the mandrel acting to propel the material from the mandrel and through the tubing so that the material comes to rest against the leading end seal of the sack being formed, whereupon the formation of the next successive end seal completes the sack and encloses the deposited charge of material. Adjustment means are provided to establish the pitch distance between adjacent sets of sealing jaws as the turret rotates to insure accurate registry of the transverse adhesive stripes with the sealing jaws both during start-up and normal operation, and phase adjustment means are also provided to initially synchronize turret rotation with tube movement. |
