It should be noted that this speed can also be modified by changing the ratio of the pulleys 35, 41.
- the wheel 37 has an octagonal shape composed of four sides having the shape of arcs of a circle connected two by two by linear sides.
- Such a wheel 37 has the advantage of not clogging and of providing better cutting results, in particular with relatively hard materials such as vinyl or synthetic materials of a certain thickness.
- the movable drawer 33 carries, moreover, means for sharpening the wheel 37 comprising two grinding wheels 42, 43 each mounted on the end of axes 44, 45 housed in blind holes 46, 47 provided on either side other of thumb wheel 37.
- One of these grinding wheels 42 is intended to give the cutting wheel its cutting angle, while the other 43 is intended to ensure the function of wire cutter.
- blind holes 46, 47 are formed so that the sharpening faces of these grinding wheels 42, 43 form a different angle of inclination relative to the corresponding face of the thumb wheel 37-
- these blind holes 46 , 47 are arranged so that the sharpening face of the sharpening wheel 42 defines an angle substantially equal to 20 degrees with the corresponding face of the wheel 37, and that the sharpening face of the thread cutting wheel 43 delimits an angle substantially equal to 5 degrees with the other face of the wheel.
- blind holes 46, 47 are arranged so that the contact of the sharpening faces of the grinding wheels 42, 43 is offset so that on contact, the rotation of the wheel 37 causes that of the said wheels.
- the means for moving these grinding wheels 42, 43 intended to apply them against the wheel are of the pneumatic type and comprise pipes such as 48, 49 for supplying compressed air opening out at the bottom of the blind holes 46, 47.
- the pressure drop in these pipes 48, 49 is also adapted so that the compressed air pressure causing the movement of the wire cutting wheel 43 is less than that causing the movement of the sharpening wheel 42 .
- This intermediate piece 50 has a central opening 51 while the drawer has a lug 52 of length less than that of the opening 51, housed in the latter, the maintenance of said drawer being ensured by a plate 53 resting on the intermediate piece 50 and fixed to the stud 52.
- the actual movements are ensured manually by means of a screw 54 cooperating with a threaded bore formed horizontally in the stud 52 so that the screwing or unscrewing of said screw causes said stud to slide inside of the opening 51.
- springs such as 55 are arranged so as to ensure effective movement of the tenon 52 when the screw 54 is unscrewed.
- This screw 54 is used once the adjustment of the base is made on the thickness of the material to be cut, so that the front contact point of the wheel 37 is located in the vicinity of the tangential servo axis and slightly offset forward relative to this axis.
- This possi bi li ty of adjustment allows t in combination with the other characteristics of the machine cutting according to the invention (very high speed of rotation of the wheel 37, quality of sharpening oe this wheel ...) to obtain an extremely attenuated cutting force, and thereby achieve the desired status , namely to get rid of any maintenance of the material to be cut.
