Abstract
An apparatus and method are disclosed for serially and automatically folding and gluing container body blanks, with optional lamination of a liner to the body blank prior to folding and gluing thereof. The apparatus includes a blank conveyor arrangement which intermittently advances a body blank along a horizontal straight-line work path through the apparatus. Arrangements are provided for applying adhesive to a flap portion of the body blank, folding the body blank about spaced parallel score lines thereof, and applying pressure to the blank to form a so-called manufacturer's joint at the flap portion. The present apparatus further includes an arrangement for advancing an inner liner into the apparatus in a direction transverse of the body blank work path, with an arrangement provided for maintaining the liner in a horizontally fixed stopped position above the blank work path, and for subsequently lowering the liner into superposition on a container body blank prior to folding and gluing of the blank.
