Of course, the shears of the folder-sectionneuse is not used on this occasion. Kind code of ref document: The present invention relates to a folder-sectionneuse for producing reinforcement frames for concrete reinforcing bars, of the type wherein a pin provided with a roller pivoted to an adjustable angle around a circular mandrel for bending round to concrete around the latter, characterized. We know that the realization of reinforced concrete structures require reinforcement shape and varied dimensions that are most often constituted by longitudinal elements bent hairpin at their ends and interconnected by wire also made frameworks folded steel.

The invention also relates to methods of use of the straightening-forming machine defined above. Similarly, the bending head 17 may be secured in a fixed position. According to the invention, the movable blade of the shears is appropriately set in the recess of the mandrel when the latter has a sufficient size. Beeton machine just described operates in the following manner. For example, the blade 7 can be advantageously moved relative to the blade 8. Otherwise, it is advantageous to secure the fixed blade of the shears with circular mandrel which thus absorbs the shearing forces generated by the movable blade that ffer located on the other side of the reinforcing rod.

As a result, without making any movement back and forth on the concrete bar 4, we can choose a short length as desired for the end of the reinforcing rod which constitutes the pin beyond the last fold.

Process for manufacturing slideway elements for the seats of motor vehicles, ships, airplanes, etc. The present invention aims to achieve a folder-sectionneuse which allows to cut reinforcing bars in the immediate Neighborhood, its last fold without having to communicate movements back beron forth.

Is schematically shown in Figure 1 a first embodiment of a folder-sectionneuse according to the invention. With machines of this type known to date, the position of the cutter which severs the reinforcing rod before the bending head requires to perform the concrete bar moving back and forth for limiting to a length normal the free end of the concrete reinforcing rod which was used to the realization of a framework.


In the embodiment of Figure 1 corresponding to the relatively large diameter of bends, the two plates 6 and 7 of the cutter may be operated independently of the mandrel 1 which undergoes accordingly none of the efforts due to shear. It is seen in Figures 3 and 4 a straightening-forming machine according to the invention comprising a straightening 10 provided with feed rollers 11 to push the concrete bar 4 from the coils 9 blockers between rollers 12 and 13 arranged in planes perpendicular.

It is seen that in both embodiments, the reinforcing rod 4 can be cut in the very near the point 6 point that is one from which concrete 4 to the round starts to be folded on itself. It furthermore comprises a cutting device, one of the blades 7 of which is located in a recess 5 of the circular mandrel 1the said recess 5 being located heton the point 6 where the reinforcing bar 4 comes into betn with the mandrel 1 at the start of the bending process.

The frames are made using another machine called clamping machine which comprises at cadreude one bending head fed by a trainer.

The various movements of the various parts of the machine which has just been described can be controlled by a microcomputer, in particular, the lengths of the different concrete round sections which are cut by the straightening, the position of the folder-sectionneuse and that of the bending head and the bending angles of each. Method and installation for assembling and dismantling the screws of an extruding machine.

When the frame is thus made the reinforcing rod 4 is advanced depending on the length of the pin that is desired and by moving the 7,8 of the shear blades to sever reinforcing bars, the liberating part of the trainer. To realize the longitudinal elements of the armatures, the straightening machine 10 is placed ger the up position with the cadrfuse In particular, it is clear that the displacement of the straightening between the high and low position can be achieved in a different way than has been shown in Figure 4.

There is shown in Figure 2 a second embodiment of the folder-sectionneuse according to the invention which corresponds to bending over a mandrel 1 of smaller diameter.

According to the invention, the mandrel 1 comprises a recess 5 in the vicinity of the point 6 where the reinforcing rod 4 comes into contact at the beginning of the folding process. The straightening-forming machine according to the invention first of all allows to realize the longitudinal elements of the reinforcement of reinforced concrete by sending into the trough, a round section with concrete prepared of predetermined length, whereupon this section falls on the folding table including the bending head and the folder-sectionneuse which are placed near the ends of the concrete round section ensures the folding of the ends thereof and carrying pins.


According to the present technique, the longitudinal members are made using a straightening machine that sends a predetermined length of yarn into a chute which discharges on a folding table cadreusf folds in the pin ends of the elongate elements.

It is understood that the reinforcing rod 4 is held in position by its right side, is caused to wrap around the mandrel 1 when the folding finger 2 and roller 3 is displaced in the direction of arrow F by pivoting about the axis of the mandrel 1. It is understood that the embodiments which have been described above presents no limiting and can receive any desirable modifications without departing from the beyon of the invention.

The invention relates to a bending-cutting machine for producing frames of reinforcement made up of reinforcing bars, of the type in which a finger provided with a roller pivots through an adjustable angle around a circular mandrel in order to bend the reinforcing bar around the latter.

It is seen from Figure 6 which is a view on a larger scale in section on VI-VI of Figure 4 the ter machine 10 and the driving rollers 11 which receive reinforcing bars straightening 4.

Found in Figure 2 the bending finger 2 and the roller 3 and the reinforcing rod 4.

To achieve the frames, the straightening machine 10 is brought into the low position by acting on the cylinder 22 while the folder-sectionneuse 16 is returned to the right.

According to the invention, the straightener 10 is mounted on a support 20 hinged in 21 on the frame of the machine while an actuator 22 is hinged at 23 on the machine aa and at 24 on the support 20 of the straightening
