Gluing machine for making boxes

Abstract

Gluing machine (10) and corresponding method for making a box starting from a pre-cut sheet, and gluing the two edges of the latter together. The gluing machine (10) comprises a fixed frame (21) having at least a first support plane (25) to support the pre-cut sheet, a first reference member (49) to align the pre-cut sheet laterally with respect to the first support plane (25), and a gluing device (46) to spread a gluing material on a fin (k) of the pre-cut sheet, or on one lateral wall of the latter in correspondence to the fin. The gluing device (46) and the first reference member (49) are supported by the same support member (31) mounted on the fixed frame (21) and mobile with respect to the latter between an inactive position and an operating position.
