Definitions

  • the invention refers to a "novel kind of calender for dressing fabrics, paper or other materials.
  • the known calenders comprise a number of rollers which generallyrest on one another (vertical calenders), or which are sometimes located side by sidelhorizontal calenders), and which are made of various materials, said rollers being subjected to pressure during operation of the calender.
  • metal rollers alternate with hard and flexible rollers made of compressed fibrous material,' for instance layers of paper or layers of fibre or of cotton or other fabric, which has been subjected to very high pressure'and'then turned "on a lathe so as to give these rollers a perfectly'cylindrical shape.
  • rollers made of compressed fibrous material which; precisely, require to be faced periodically, they are diflicult to remove; furthermore, owing to the difference which soon appears in their diameters or in their hardness, and by the fact of the very heavy;pressure to which they are subjected and of their contact with the heated metal rollers, local heating occurs at their periphery which may quickly deteriorate them.
  • the purpose-of theinvention- is to eliminate all the drawbacks of the classical types of calenders, and it has for its object a calender-of a novel kind which is characterized, in principle, by the fact that it comprises a set of lower rollers mounted on a fixed frame, a central roller made of compressed fibrous material resting on said lower rollers, and a'set' of upper rollers resting on'the'central' fibre roller, the upper rollers and the central roller being mounted on a common upper frame-adapted-to receive a lifting movement relatively to the fixed frame supporting the set of lower rollers, and the central fibre roller being, furthermore, mounted in the common upper frame which can be lifted so as to enable it to move away from the upper rollers and the lower rollers owing to the actual lifting of the said upper frame.
  • Fig. 1 is a View inside elevation of "the calender, of which Fig. 2 is a'view in front elevation,-
  • Fig; 3' being a diagram of the transmission of' the movement to the metal rollers driving the fiber roller by contact.
  • l is the lower frame carrying the lower set of metal rollers 2 and 3; 4 are are areshaped lateral arms'ada'ptedto pivot 'about a spindlei 0f the frame I andcarrying the upper
  • each-supporting arm 4 is pivotally connected to the upper part forming a clevis m of a rod Ill which is pivotally connected at its other end lil to a lever II adapted to pivot at l2 on the frame I, the two levers H accommodating at the rear end means enabling the pressure which they exert on the upper frame 4 and, consequently, on the rollers of the calender, to be varied, for instance weights I3, the number of which can be altered at will.
  • this set of levers may be replaced by a hydraulic device, also of known type.
  • I6 designates the fabric subjected to calendering, ii a roller mounted on a rear support l8 and receiving the fabric as it comes out of the machine, 19 a mechanical folder of known type, and 20 a carriage receiving the folded fabric.
  • the drive of the metal rollers 2 and 3,6 and 'l is obtained, for instance, by means of an electric motor 2
  • the upper roller "i may be made of fibrous material.
  • a calender a fixed lower frame, an arcshaped upper frame pivoted for swinging movement with respect to said lower frame, lower rollers fixedly mormted for rotation on said lower frame, upper rollers fixedly mounted for rotation on said upper frame, a central roller positioned between said upper and lower rollers, spaced parallel guide lugs depending from said upper frame, said guide lugs being provided with elongated slideways having upper and lower limits, said central roller having axles engaged for sliding movement within said slideways and bein -adapted to be lifted upon swinging movement of said upper frame to the extent that said axles abut against said lower limits whereby disengagement of said central roller from said upper and lower rollers will be brought about;
  • a calender having an upper and a lower frame; lower rollers mounted on said lower frame, upper rollers mounted on said upper frame which is pivotally connected at one of its ends for swinging movement to said lower frame, a central roller positioned between said upper and lower rollers, guide lugs on said upper frame and provided with vertical slideways, and stubaxles removably mounted on said central roller and loosely engagingsaid slideways, said slideways terminating in upper and lower ends, whereby upon initial outward swinging movement of said upper frame away from said lower frame said central roller engages said lower ends and will be spaced from said upper rollers "and subsequently upon completion of said outward movement be disengaged from said lower rollers.
  • a calender according to claim 1 in which said guide lugs form an integral part with said upper frame from which they extend in the direction of said central roller.
