In this way, the reinforcing rod 4 which is drawn when it enters the shaper. 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 which folds in the pin ends of the elongate elements. 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.

This recess is intended to receive the blade 7 of a shears the other blade 8 is disposed on the other side of the reinforcing bars 4.

The present invention relates fe a folder-sectionneuse to achieve particular round frames concrete and universal trainer-forming machine using this folder-sectionneuse to achieve concrete round frames and the use of the latter for the manufacture of armatures. The frames are made using another machine called clamping machine which comprises at least one bending head fed by a trainer. Of course, the shears of beeton folder-sectionneuse is not used on this occasion.

The trainer 10 then advances the concrete bar 4 of a length corresponding to one side of the frame and the folding roller 3 performs the folding of the reinforcing rod 4 and so on until the formation of the different sides of the frame.

With a device of known type, for example by tilting the chute 14 discharges the concrete 4 round section standing on the folding table 15, the folder-sectionneuse 16 and 17 fold the head have been previously brought into position which depend on the length of the concrete round section 4.

According to the invention, the latter comprises a chute 14 disposed above a folding table 15, which comprises, firstly, a folder-sectionneuse 16 according to the invention of the type represents- in Figures 1 and 2 and secondly a bending head The shear stress between the two blades 7 and 8 is constructed in the known manner, for example by means of a hydraulic or pneumatic cylinder.

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. 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. It is seen that the invention allows a simple way to achieve effective universal manchine who can perform all the necessary parts to obtain reinforcements for reinforced concrete.

The trainer 10 then sends the folder-sectionneuse 16 a round length in concrete 4 such that the latter exceeds the brake 16 sufficiently to make a hook which is obtained by pivoting of the folding roller 3 Fig 1 and 2. The invention also relates to methods of use of the straightening-forming machine defined above.

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.

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.

Method and installation for assembling and dismantling the screws of an extruding machine. 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 frame and at 24 on the support 20 of the straightening 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.

Sur ce dessin, On this drawing. Pipe conduit bending machine and method of making a pipe conduit with a soldered joint. In this way, thanks to the actuator 22, it is possible to tilt the straightening machine 10 about its hinge axis 21 between two positions, namely a high position in which the reinforcing rod 4 comes out of the straightening machine 10 is in the axis of the chute 14 and a low position in which the reinforcing rod 4 comes out of the straightening machine 10 is located in front of the bending head 17 as shown by 4 in Figure 5.


Profiling machine for finished or semi-finished prods. It is seen from Figure 6 which is a view on a larger scale in section on VI-VI of Figure 4 the straightening machine 10 and the driving rollers 11 behon receive reinforcing bars straightening 4. Similarly, the bending head 17 may be secured in a fixed position.

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. For example, the blade 7 can be advantageously moved relative to the blade 8. Is schematically shown in Figure 1 a first embodiment of a folder-sectionneuse according to the invention.

Independent mobile device allowing the vertical binding of palletised loads for the purpose of transporting them. In this embodiment, the fixed blade 7 of the shears is integral with the mandrel 1, while the movable blade 8 cuts the reinforcing rod 4 which is supported on the blade 7, which is supported by the chuck 1 which is integral the frame of the machine. Also shown in this figure, the bending head 17, which is constituted by a mandrel 18 against which abuts a concrete bar 4 which is pressed by a movable finger 19 which is provided with a not shown roller and which can be rotated around the mandrel 18 by a predetermined angle to make the concrete round the folding around the mandrel 4.

Machine and working cycle for making plastic bags with a zip fastener and device for positioning them. The machine just described operates in the following manner.

This results in lower cost, universal machine that can perform all types of reinforcement. Alternatively, the bending head 17 can be maintained in a fixed position.
