The transfer machine extends between the die-cut blank erecting station and the discharge conveyor on which the resulting boxes are carried away. It has a carriage that moves lengthwise underneath the sole plate of the various stations over which the box blank progresses. The carriage carries a system of clamps having movable upstream and downstream arms for gripping the blanks and a pusher. Together, the clamps and the pusher are used to move the blanks along the sole plate and push the box onto the discharge conveyor. The arms and the pusher are situated on a plate which is vertically movable relative to the carriage and the height of the projecting part of the upstream arms is greater than the height of the downstream arms and than that of the pushers. The upstream arm couple is hinged to the plate and pivots to allow it to retract upstream relative to the machine and beneath the sole plate. This pivoting of the arm couple is combined with the up-down movement of the plate.

What is claimed is: 1. Device for transferring cardboard box blanks for a wrapping and packaging machine, which device extends between a station for forming cutouts and a conveyor for removing boxes obtained, which transfer is carried out according to a cycle that comprises operations of erecting a cardboard cutout, filling the box blank obtained and pressing said blank at a pressing station in order to transform the blank into a box,which device includes at least a carriage that moves longitudinally under a plurality of stations, including the pressing station and a forming station, on a guide system comprising tracks and/or slides, which guide system is parallel to a soleplate of said wrapping and packaging machine, that extends over the entire length of said stations and on which said box blank advances, which carriage has at least a clamp system comprising mobile upstream arms and downstream arms for gripping said blanks and boxes, and a push member, in which the clamp system and push member enables said blanks and boxes to be moved on said soleplate, then pushed onto said removal conveyor,which upstream and downstream arms, respectively, are arranged in pairs on a plate that is vertically mobile with respect to said carriage in order to move said arms either into an active position for handling the blank when the blank is assembled on said soleplate at the forming station, or into an inactive position below said soleplate after said box has been released at the pressing station; andwherein the upstream arms comprise a projecting portion that is greater in height than that of the downstream arms and push member, which upstream arms are pivotably connected to the plate and pivot about a horizontal shaft, perpendicular to the movement of the carriage, to enable movement into the inactive position by retraction upstream of the machine and below the soleplate of the various stations when said carriage returns and then movement into the active position for handling the blank during the transfer movement performed by said carriage.
