ABSTRACT:
In an automatic carton closing machine, adjustable holding mechanism for a pair of elongated longitudinal clamping rails which converts them to laterally spaced side guide rails extending through the machine to define a path of carton forward travel therebetween and provides sliding clearance for all loaded cartons of a group intended to be of about the same size while accommodating small degrees of variances in widths thereof. For this purpose there are provided means to move at least one of the pair of side guide rails inward toward the other to cause them to be spaced apart with location thereof closely adjacent to opposite sides of a loaded carton of a single size group as it enters the machine for forward guided transport therebetween past flaps manipulating and anchoring mechanisms of the machine, and means to adjust such spacing between these rails to assure attainment of the desired relatively small degree of additive tolerance.
