The working system can prevent a bending failure due to the positional misalignment of the workpiece before, in the middle of, and after bending.
The second bending surface (136) rotates with respect to the first bending surface (124) during a bending operation.
Bending can be effected by means of roller profiling or swage bending.
The back comprises a bending line (2) or a portion (3) between two bending lines (2) outside the folding portions.
Bending of the core causes the flexible body to be bent in a similar manner.
Each folder group comprises three folding members which carry out the folding and all movable folders are mounted on the packing head.
This body folding device for carrying out the body folding method for an outer packing material has first and second body folding guides (66, 68).
The invention relates to a folding device (2) and a folding method, said folding device (2) having a folding bed (14) for a workpiece (3) and multiple folding robots (8, 9) with folding tools (20).
The lower folding member includes a plurality of folding blades and the upper folding member includes a plurality of radial fold fingers.
The folding is carried out by means of a folding plate (12) of which the folding face (16) comprises even towards the folding end a significant folding component which is parallel to the extremity (31) of the edge.
The folding slide (3) has at least one first folding surface (13) and a second folding surface (14).
Folding along fold line (32) results in the flap (26) being folded against the second panel (28).
The first edges (40) extends in general alignment with the transverse foldlines, respectively.
The invention relates to a roller folding head.
The folder may include a folder platen (130) having an associated folder bar (150) to fold said strip material (2).
The second fold line is oblique relative to the first fold line.
The first fold line and the second fold line are nonparallel.
The bending is performed using the bending tool which is guided such that during the bending no relative displacement of the point of contact between bendind tool and leads for bending takes place.
Bending hours and bending costs are calculated from the bending processes.
A metal bending apparatus includes a carrier bearing at least one bending tool.
The bending position (13a) may be provided with holes for making bending easier.
The device comprises a bank (40) of bending stations (40a) positioned side by side and fitted with fixed benders (23) and moving benders (90).
The housing lid (5) of the housing (3) is then permanently fixed using a rolling device (10), by moving a housing rolling edge (9) which is located on the housing (3).
Also, the left longitudinal folding line is parallel with the right longitudinal folding line and they are both positioned under the front transverse folding line.
The invention is applicable to devices for folding parietal implants.
The machine (100) is, furthermore, equipped with a folding section (150) comprising a couple of folding rollers (8a, 8b) having a linear folding speed, VP.
The method further provides to transfer said fed bars to a first folding bench (10, 100) and to a supplementary folding bench (20, 200) of the apparatus for performing the folding thereof according to respective folding cycles.
Folding means (9) for force-folding a tarpaulin are provided in the vicinity of the slides (6).
The album content sections are splitted by a plurality of spaced fold-lines and using the fold- lines a zigzag fold may be formed.
A sheet folding apparatus is described including a fold blade, a clamp movable to engage the fold blade, and a fold blade receptacle having two flexible spring members.
The shoulder and the side panels are provided with fold lines to facilitate folding of the body.
Firstly, the continuous piezoelectric element (10) may have a bender construction such as a bimorph bender construction.
The folding and wrapping continues until one of the folding lines reaches the third guideline.
In addition, the turret cluster position in the center allows for bending support with mandrel bends or nose bending on the back side of the bending head, usually 180 degrees away from the normal bending area.
According to the invention, the signatures (78) are pressed into a pre-folding, gripping element system (28) by means of a folding blade (23).
The pressure difference also generates a bending force to reduce the bending curvature of the substrate.
