Device for printing Braille characters on cardboard blanks travelling in a folder-gluer along a substantially planar path, the device comprising rotary embossing tools carried by two respective parallel shafts rotatably mounted above and below of the plane of said path and operable for printing Braille characters on their blanks during their run through the folder-gluer. The tools are supported on shafts and the tools are adjustable axially and angularly with respect to each other.

Braille printing device

This retractable central conveyor (,) being used in a folder-gluer converting plate-like workpieces such as paper or cardboard for producing packagings. Such a folder-gluer comprises two frames between which are arranged two lateral conveyors (,), the conveying means of which being belts (,). The conveyor of the present invention comprises a structure consisting of four associated components (,) which are transversely movable between the frames of the folder-gluer with respect to the travelling direction of said plate-like workpieces. Among these components of this structure, an upper longitudinal bar (,) can easily be manually lowered, in a vertical slanted movement, from a working position to a retracted position, and inversely raised by independent damping means (,). The central conveyor (,) can be retracted between the two lateral conveyors (,) thus enabling the folder-gluer to be used in a new configuration where uncoupling of the transmission means necessary for the independent drive of the belt (,) is not required and which belt (,) is rotatable even in the retracted position. This conveyor allows to arrange the two lateral conveyors (,) side by side so that the useable conveying width of the folder-gluer is reduced to a minimum value.

Retractable central conveyor in a folder-gluer

A device for aligning box blanks in a box blank processing machine including a frame supporting a lengthwise guiding rail, an upper carrier and lower carrier which are directly interconnected by brackets and have one end pivotably mounted to the frame adjacent an exit end of the device so that the entrance end of the carriers can be spaced from the rail to provide a lateral movement of a blank against the rail. The position of the entrance end of the carriers is adjustable relative to the guide rail. The upper carrier preferably is formed of a series of rollers and the lower carrier has a series of rollers supporting a belt which is driven by a drive pulley.
