A new and improved case former, or carton folding and erecting apparatus, is disclosed wherein a pair of pivotal support arms, upon each one of which is mounted a case or carton engagement roller, are mounted upon the machine framework such that when actuator mechanisms, for folding the oppositely disposed major side bottom flap members of the case or carton to their folded positions so as to complete the formation of the bottom portion of the case or carton, are actuated, the pair of pivotal support arms are effectively released from a restrained position, at which case or carton engagement rollers are disposed at retracted positions with respect to the case or carton blank so as to initially permit the case or carton blank to be inserted into the case former, or carton folding and erecting apparatus, in an unobstructed manner, whereby the case or carton engagement rollers can now engage the major side walls of the case or carton so as to retain the case or carton in position while the case or carton is subsequently filled with product.

A case forming machine for forming a bottom wall member of a case from a case blank comprising a pair of oppositely disposed minor end wall members, a pair of oppositely disposed major side wall members, a pair of oppositely disposed minor end wall bottom flap members, and a pair of oppositely disposed major side wall bottom flap members, comprising: a framework defining an interior region within which a case blank is to be disposed so as to have a bottom wall member formed thereon from a pair of oppositely disposed minor end wall bottom flap members and a pair of oppositely disposed major side wall bottom flap members; first means mounted upon said framework for folding the pair of oppositely disposed minor end wall bottom flap members upwardly and inwardly so as to partially form the bottom wall member of the case; second means mounted upon said framework for folding the pair of oppositely disposed major side wall bottom flap members upwardly and inwardly so as to complete the formation of the bottom wall member of the case; and engagement means movably mounted upon said framework, independent of said first and second means for folding the pair of oppositely disposed minor end wall bottom flap members and the pair of oppositely disposed major side wall bottom flap members, between a retracted position at which said engagement means will be located away from said interior region of said framework so as to permit the case blank to be inserted into said interior region of said framework, and an extended position at which said engagement means will project into said interior region of said framework so as to engage at least one of the pairs of oppositely disposed major side wall members of the case so as to fixedly secure the case blank within said interior region of the framework while the bottom wall member of the case is being formed by folding the pair of oppositely disposed minor end wall bottom flap members and the pair of oppositely disposed major side wall bottom flap members upwardly and inwardly. 8. The machine as set forth in claim 7, wherein: said engagement means comprises a pair of engagement rollers. 9. The machine as set forth in claim 8, wherein: said engagement means comprises a pair of support arms which are pivotally mounted upon said frame members, and which have said pair of engagement rollers mounted thereon. 10. The machine as set forth in claim 7, wherein: one of said first and second means mounted upon said frame members for folding one of the pairs of oppositely disposed minor end wall bottom flap members and the oppositely disposed major side wall bottom flap members upwardly and inwardly, comprises a pair of roller arrays which are pivotally movable between a retracted position at which said pair of roller arrays are disengaged from one of the pairs of oppositely disposed minor end wall bottom flap members and oppositely disposed major side wall bottom flap members, and an extended position at which said pair of roller arrays are engaged with one of the pairs of oppositely disposed minor end wall bottom flap members and the oppositely disposed major side wall bottom flap members, so as to fold one of the pairs of oppositely disposed minor end wall bottom flap members and the oppositely disposed major side wall bottom flap members upwardly and inwardly so as to thereby form a part of the bottom wall member of the case, and wherein further, said pair of roller arrays together form a roller conveyor upon which the case is supported. 11.
