Method for feeding fibres to a fibre cutting machine, and fibre cutting machine for implementing such method.

Wire pay-off station for wild spooled coils

Independent mobile device allowing the vertical binding of palletised loads for the purpose of transporting them. Similarly, the bending head 17 may be secured in a fixed position. Sur ce dessin, On this drawing. 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. A1 Designated state s: Found in Figure 2 the bending finger 2 and the roller 3 and the reinforcing rod 4.

It furthermore comprises a cutting device, one of the blades 7 of which is located in geton 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. The trainer-forming machine according to the invention also makes it easy to achieve even small frames thanks to the fact that the folder-sectionneuse which is close to the trainer allows to cut reinforcing bars near the last bend without communicate a back and forth.

As a result, without making any movement brton 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. 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.

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 order to better understand the invention, will now be described by way of illustration and not limitation, an embodiment taken as an example and shown in the accompanying drawing.

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 is located on the other side of the reinforcing rod. The machine just described operates in the following manner. This folder-sectionneuse comprises in known manner a circular folding mandrel 1 and a folding finger 2 which is provided cadreuze its end with a roller 3 which can be pivoted about the axis of the mandrel 1.

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.

Process for manufacturing slideway elements for the seats of motor vehicles, ships, airplanes, etc. 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.

Pipe conduit bending machine and method of making a pipe conduit with a soldered joint. 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. 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 and forth.

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 caddeuse the blade 7, which is supported by the chuck 1 which is cadfeuse the frame of the machine. The present invention also aims to provide a single machine which, by the combination of its elements, allows to achieve both the longitudinal elements and the reinforcement frames that meet them.

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.

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. 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.

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. Of course, the shears of the folder-sectionneuse is not used 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 the manufacture of armatures. According to the present technique, the longitudinal members are made using a straightening machine that sends a predetermined length q yarn into a chute which discharges on a cadreus table which folds in the pin ends of the elongate elements.

The invention also betkn to methods of use of the straightening-forming machine defined above. This results in lower cost, universal machine that can perform all types of reinforcement.

Is schematically shown in Figure 1 a first embodiment of a folder-sectionneuse according to the invention. In the embodiment of Figure 1 heton 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 that in both embodiments, the reinforcing rod 4 can be cut in betoon very near the point 6 point that is one from which concrete 4 to the round starts to be folded on itself.

Machine de cadre & étrier ( cadreuse automatique )

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. 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 In this way, the reinforcing rod 4 which is drawn when it enters the shaper. 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.
