ABSTRACT:
An apparatus for manufacturing a laminate having a width of at least 30 cm. by means of a solventless adhesive, wherein, in a first stage, means are provided for continuously supplying a solventless adhesive to a distributor means comprising a pre-dosing element and an elastic-surfaced rotating element in such a manner as to coat the surface of the elastic-surfaced rotating element with a layer of solventless adhesive having a thickness of from 5 to 50 microns, the layer then being substantially transferred to a moving film to be laminated, the circumferential speed of the elastic-surfaced rotating element and the speed of linear displacement of the film being in a ratio of from 1:10 to 1:50, so that the film receives a layer of solventless adhesive of a thickness of from 0.5 to 5 microns, and, in a second stage, means are provided for bonding in a known manner the film coated in this manner to another film to form a laminate.
