This invention involves a system for minimizing the formation of glue drops on picks used to separate a sheet from the surface of a glue applicator drum from which a coating of adhesive is applied to the sheet. Spreader means are provided to wipe from the upstream surface of the drum at least a major portion of the adhesive that lies in the path of each pick.

Glue applicator apparatus and method

An improved apparatus for and method of making laminate articles is described. The invention is particularly useful in making bookcases of the type including relatively stiff front and back cover backing sheet members and a flexible spine backing sheet member. One edge of each of the stiff and flexible backing sheet members is substantially aligned with one another, with the flexible backing sheet member precisely centered between two stiff backing sheet members. The substantially aligned edges are registered with respect to an edge of a sheet of material and the outer opposing edges of the stiff backing sheet members are precisely spaced from one another and registered with respect to a second adjacent edge of the sheet of material. The members are then brought into contact with and laminated to the sheet of material. The improvements include feeding, cutting and supporting mechanisms for the flexible spine sheet member.
