ABSTRACT:
An apparatus for effecting synchronous, in-line placement of pads of material, such as a highly absorbent compressed composite laminate, includes a supply reel for supplying a continuous web of material. The web of material is guided to a pair of pull rolls which effect movement of the web at a first velocity V.sub.1. A cutting mechanism, preferably comprising cooperating knife and anvil rolls, cuts individual discrete pads of the material for presentation to an associated vacuum transfer drum. The vacuum transfer drum includes a peripheral surface operated at a second velocity V.sub.2 equal to or greater than the first velocity V.sub.1, with the velocity V.sub.2 equal to the linear speed of movement of an associated continuous substrate, such as comprising air laid comminuted wood pulp. The discrete pads of material are thereby transferred onto the substrate at a relative spacing S between adjacent ones of the discrete pads, which spacing equals L(V.sub.2 -V.sub.1)-L.
