Abstract: In order to improve a bending machine for flat material, comprising a machine frame with lower and upper clamping tools arranged on the machine frame, with which the flat material can be fixed in a clamping plane, a bending tool moving device, with which a bending tool carrier with a bending tool for bending the flat material about a bending edge relative to the clamping plane can be moved into a plurality of bending positions, in such a manner that with a space-saving construction of the bending machine the movements of the bending tool can be realized technically with simple means it is suggested that the machine frame be designed to be laterally open at at least one of its transverse sides for the insertion of flat material in longitudinal direction of the bending edge and between the upper beam and the lower beam, that the bending tool be movable transversely to the clamping plane for passing through the bending positions and that the bending tool carrier remain exclusively on the side of the clamping pla

Abstract: A bending machine for flat material, comprising a lower beam and an upper beam, with which the flat material can be fixed, a lower as well as an upper bending tool moving device, with which the bending tool not used for an operation on the flat material can be brought into a rest position, in which a bending space free from machine elements of the bending machine exists between the clamping plane and the bending tool located in the rest position and its bending tool carrier, this space extending over an angular area of at least 100° around the respectively operative bending edge.

Abstract: In order to improve a bending machine for flat material, comprising a machine frame, a lower beam arranged on the machine frame and an upper beam arranged on the machine frame, with which the flat material can be fixed in position, a bending tool moving device, with which a bending tool can be moved, in such a manner that the movements of the bending tool can be realized technically with simple means and precise bending movements of the bending tool can be carried out it is suggested that the bending tool have a bending nose with a curved pressure surface for acting upon one side of the flat material and that the bending tool be movable by the bending tool moving device between a starting bending position and an end bending position on a path about the respective bending edge which is predetermined in a defined manner such that the curved pressure surface and the side of the flat material acted upon move relative to one another in the form of an essentially slide-free rolling on one another.

Abstract: In order to improve a folding machine for joining the edges of two sheet-metal parts forming an angle between them by means of a folding procedure, comprising a machine frame, a folding carriage movable on the machine frame by a drive in a guide means extending along a folding direction, this carriage having at least one pair of folding rollers for folding the edges of the sheet-metal parts, and holding devices arranged on the machine frame for fixing the sheet-metal parts in position during the folding procedure, such that large, in particular, long sheet-metal parts can be handled in a simple manner on this machine and are easy to insert into it, it is suggested that the guide means be movable in an essentially vertical direction, and that the folding machine have support surfaces arranged on a supporting plane extending at right angles to the folding direction, the sheet-metal parts being placeable on these support surfaces with edges which extend transversely to the edges resulting in the fold.

Abstract: Plate shears for flat workpieces, especially sheet metal, comprise a fixed lower blade (4), an upper blade (6) secured to a vertically movable blade beam (8), a cutting bench (2) arranged in front of the blades, a swivel roller bench (11) comprising several parallel rows of rollers (12) arranged behind the blades, the swivel-roller bench can be swivelled about an axis (D) substantially parallel to the cutting region of the blades and can also be moved back and forth in relation to the blades, and an adjustable stop (3) arranged behind the blades for workpieces to be cut to a given width. Swivelling of the swivel-roller bench downwardly simultaneously lowers the front of the swivel-roller bench which is closer to the lower blade.

Abstract: A rotating radial unit has bottle receiving recesses on its periphery for accepting bottles from a linear conveyor. A pair of elements are mounted on the unit adjacent each receiver for moving towards and away from the receiver. A belt runs around rolls that are on both elements so portions of the belt grip a bottle on each side when the elements are moved toward each other automatically. A motor can drive the belt to rotate the gripped bottle as it is transported on the unit. A sensing device controls the motor to start and rotate the bottle and to stop when a marker on the bottle is rotated to a preferred orientation or alignment so a series of bottles will be aligned identically as they are released. The elements are automatically spread apart to release the grip of the belt on the bottle.
