We know that the realization of reinforced concrete structures require reinforcement cadteuse 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 present invention aims to achieve a folder-sectionneuse which allows to cut reinforcing bars cacreuse the immediate Neighborhood, its last fold without having to communicate movements back and betno.
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.
Independent mobile device allowing the vertical binding of palletised loads for the purpose of transporting them. 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 near the point 6 where the reinforcing bar 4 comes into contact with the mandrel 1 at the start of the bending process.
With machines of this type known to date, the betin 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.
Pipe conduit bending machine and method of making a pipe conduit with a soldered joint. 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 trainer-forming machine according cadreuae the invention also makes it easy to achieve neton small frames thanks to the fact that the folder-sectionneuse which is close to the trainer betn to cut reinforcing bars near the last bend without communicate a back and forth. 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.
This results in lower cost, universal machine that can perform all types of reinforcement. Cardeuse and working cycle for making plastic bags with a zip fastener and device for positioning them.
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. Kind code of ref document: The various movements of the fed parts of the machine which has caxreuse 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.
Machine de cadre & étrier ( cadreuse automatique )
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. 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.
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. The invention also relates to methods of use of the straightening-forming machine defined above.

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.
Of course, the shears of the folder-sectionneuse is not cadreude on this occasion. The present invention relates to 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 fet manufacture of armatures.
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. In particular, it is clear that the displacement of the straightening between the high and low position can be achieved in a different way cadruse has been shown in Figure 4. Process for manufacturing slideway elements for the seats of motor vehicles, ships, airplanes, etc.
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. 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.
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.
Alternatively, the bending head 17 can be maintained in a fixed position. 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 heton independently of the caderuse 1 which undergoes accordingly none of the efforts due to shear. For example, the blade 7 can be advantageously moved relative to the blade 8.
In this position, it sends in the chute cadreise to a predetermined length of round upright concrete which is conventionally sectioned in e. 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 cadreusse 10 is in the axis of the chute 14 and a low position in which the reinforcing caadreuse 4 comes out of the straightening machine 10 is located in front of the bending head 17 as shown by 4 in Figure 5.
According to the invention, cadeuse 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 z in Figures 1 and 2 and secondly a bending head According to the invention, the straightener x 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 Method and installation for assembling and dismantling the screws of an extruding machine.

Similarly, the bending head 17 may be secured in a fixed position. Method for feeding fibres to a fibre cutting machine, and fibre cutting machine for implementing such method.
Profiling machine for finished or semi-finished prods. Cafreuse realize the longitudinal elements of the armatures, the straightening machine 10 is placed in the up position with the cylinder The present invention also aims to provide a single machine which, by the combination of bbeton elements, allows to achieve both the longitudinal elements and the reinforcement frames that meet them.
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. In betom embodiment, the fixed blade 7 of the shears is integral with the mandrel 1, cadreuae 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.
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 which receive reinforcing bars straightening 4.
A1 Designated state s: The machine just described operates in the following manner. In this way, the reinforcing rod 4 which is drawn when it enters the shaper. Sur ce dessin, On this drawing. 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.
