摘要:
The invention concerns a peeling device arranged downstream of a rotary machine for cutting out cardboard blanks (4) comprising a housing (1, 1') provided with elements supporting (9, 11) two shafts (5, 5') driven synchronously in rotation and supporting rotary elements (7, 7') between which is driven the cut out cardboard blank, one of said elements (7, 7') comprising prehensile means (8) for grasping the peel (4) so as to separate it from the rest of the blank (4'). Said device is characterised in that the elements supporting (9, 11) the shafts (5, 5') comprise maintaining means (15, 16) enabling the latter to be fixed and removed and angular indexing means relative to those of the two shafts (5, 5').
摘要:
The invention relates to a device for scaling cut-out cardboard blanks (2, 2') comprising the high-speed (1,4V) ejection means (I) of a cutting machine and low-speed (V') receiving means. The inventive device is characterised in that it is provided with an intermediate adjusting module (II) whose at least blank-driving speed is adjustable and which is arranged between the ejection means (I) and the receiving means (III).

The invention concerns a device for positioning a plate (3) on a roll (1), in particular a chopper or folding roll. Said device is characterised in that the roll is provided with magnetic fixing means maintaining the plate on the surface thereof, and two centring elements whereof at least one (9) is mobile and longitudinally spaced apart from the first, so as to co-operate with matching means maintaining the plate (3), the mobile centring element (9) being linked to control means (15) for displacing it along the transverse axis of the roll (1).
摘要:
The present invention relates to a straightening device (1) for straightening a sheet of material (2), for example cardboard, supplied continuously from a reel (3). Said device is characterized in that the supports (14, 15) of the bearings (12, 13) of both return cylinders (5, 6) form guides for the bearings (12, 13) mounted movably on said supports, and linking means (16, 17) are provided between the movable straightening block (8) and the bearings (12, 13) of the return cylinders (5, 6) so as to reduce the distance (d) between the axes of the two return cylinders (5, 6) as a function of the amplitude of the V deformation of the sheet (2), and also to compensate automatically the variation of the length of said sheet.
摘要:
A device for selecting cut paperboard blanks as they are fed between at least two series of drive belts (1, 2, 3, 4) defining an upper path and a lower path. Said device comprises a path selection means consisting of a flap (6) pivotably mounted about a downstream shaft (O) capable of being placed in two positions, i.e. a normal operating position in which the blanks (8) are fed to the upper path, and a selection position in which the blanks (8) are fed to the lower path. The device is characterised in that the upper path of the drive belts (1, 2, 3) driving the blanks (8) is curved, at least in the upstream and downstream portions adjacent to the pivotable flap (6), with a substantially uniform radius of curvature, and the upper rear surface (6a) of the flap (6) has a curvature adjacent to that of the belt extending thereabove, so that in the selection position, it defines therewith a substantially parallel path.
