The working system can prevent a bending failure due to the positional misalignment of the workpiece before, in the middle of, and after bending.

Bending of the core causes the flexible body to be bent in a similar manner.

The method of bending the metal sheet consists in heating and bending thereof with the use of gravity.

Bending can be effected by means of roller profiling or swage bending.

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.

Thus, the vertical folding shown in Fig. 4, the lateral folding shown in Fig. 12, and the disassembly shown in Fig. 29 can be realized.

Folding can be longitudinal before lapped, superjacent opposing folding.

The invention relates to a bending device for the profile bending of elongated profiles, comprising at least one supporting roll, located at the intake end of the device, which lies against one side of the profile to be bent.

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.

Assembly and folding of the pet crate are very convenient, also facilitating folding and unfolding.

The bending position (13a) may be provided with holes for making bending easier.

The apparatus includes an arrangement for inducing bending of the laminate and an arrangement for controlling the bending.

A pair of plate benders are provided for bending a bone plate.

The shoulder and the side panels are provided with fold lines to facilitate folding of the body.

The introduced domain interferes an interdomain interaction during protein folding and inhibits the folding by the interferential action.
