Definitions

  • the sheet or thin strip When the sheet or thin strip is to be wound onto the mandrel, it is generally essential to cause the sheet or the strip to adhere to the external wall of the mandrel for a sufficient length of time to enable the total adhesion force resulting therefrom to overcome the various frictional forces by which the sheet or the strip is retained upstream so that no slip occurs on the mandrel.
  • the sheet to be wound is forced into contact with the exterior surface of the mandrel by a belt means which is intended to keep the sheet applied against the mandrel during the initial phase of the winding operation.
  • a belt means which is intended to keep the sheet applied against the mandrel during the initial phase of the winding operation.
  • this type of accessory is cumbersome, occupies a relatively large amount of space, and in addition, since the product to be wound is generally a thin metallic sheet, the edge of the sheet bears against the belt, whereby the latter becomes worn and this is more particularly true when the sheet has been cold-hardened with its longitudinal edges then being sharp.
  • the present invention concerns a new apparatus for winding sheet or strip-like material onto a mandrel and permits the coiling of said material to be achieved without the aforesaid disadvantages.
  • the oppositely disposed surfaces of the sheet material to be wound are subjected to different pressures, the value of the pressure which is exerted on the inside surface of the sheet always being lower than that exerted on its outside surface.
  • the higher pressure exerted on the outside surface of the sheet is that of a fluid emanating from a source or a reservoir and being under a superatmospheric pressure with the inside surface of the sheet being subjected only to ambient pressure.
  • it is the outside surface of the sheet which is subjected to ambient pressure, while the inside surface thereof is subjected to a negative pressure, said pressure being exerted through apertures or perforations extending from the hollow core of the mandrel radially through the wall thereof.
  • the mandrel on which the winding is effected is situated within an expansible housing comprising substantially complementally formed half portions which are adapted to pivot about a common axis, so as to be able to move laterally away from the mandrel to enable the finished coil to be withdrawn with the housing halves providing between them means defining an opening which forms a longitudinally extending slotted area through which the free end of the sheet or strip to be wound can be introduced.
  • FIG. 1 illustrates an end elevational view of an apparatus constituting a first embodiment of the invention
  • FIG. 2 illustrates the apparatus of FIG. 1 in top plan view
  • FIG. 3 is a partial sectional view along line II of FIG. 1 with the mandrel removed;
  • FIG. 4 is a developed view indicating one of the possible patterns of apertures in the wall of the half housings of the apparatus according to FIGS. 1, 2 and 3;
  • FIG. 5 is a cross-section through the apparatus constituting the second embodiment of the invention taken along plane 5-5 of the following FIG. 6;
  • FIG. 6 is a section along line 6-6 of FIG. 5;
  • FIG. 7 is an auxiliary means to complete the effect of a positive or negative pressure.
  • the housing surrounding the mandrel is in the form of two complementally formed separable elements illustrated by way of example as two half casings or portions 1 and 2 which may have any desired external contour but which define a cylindrical internal cavity extending coaxially relative to the mandrel 9, the internal diameter of the cavity being substantially larger than the external diameter of the mandrel 9.
  • the cavity is arranged to be closed in a fluid-tight manner at its oppositely extending two end portions by spaced walls 14 and 15, only the means forming the gap 3 being left open to the atmosphere for the introduction of the leading edge of sheet 4 which is to be wound.
  • pivoting axis which is common to the two half casings 1 and 2 which may generally be moved laterally away from their operative position as shown in FIGS. 1 and 5 at the end of the winding operation by pivoting in the direction of the arrows 6 and 6a so that the wound coil may be removed.
  • a cylindrical duct 7 comprising at its free end an annular flange 8 which enables the duct 7 to be connected by means of a flexible conduit to a source of supply which produces a suitable fluid under pressure.
  • the internal walls 10 and 11 of the two half casings are formed with apertures more or less regularly distributed over the surface area thereof and intended to permit the emission of the fluid under pressure into the central cavity surrounding the mandrel, with the jets of pressurized fluid therefrom all being directed substantially radially toward the mandrel.
  • At 12 there is shown only generally a motor-driven gear reduction unit by which the mandrel is appropriately rotated.
  • FIGS. 3 and 4 illustrate merely by way of example arrangements of the apertures 13 which are of elongate form and are disposed over the whole surface areas of the cylindrical Walls 10 and 11 as shown.
  • the apparatus of the first embodiment operates as follows: On being introduced through the means defining the opening or gap 3 into the internal cavity of the expansible housing, the free end area of the sheet or Strip to be wound is urged against the surface of the mandrel by the emission from the first jets of fluid with which it comes into contact. As the sheet or strip is pulled by the mandrel with its end travelling farther into the cavity in the casing, additional fresh jets of fluid to which it is exposed in its passage into said casing constantly maintain it against the mandrel, whereby the surface on which the action of the fluid is exerted, is gradually increased.
  • the action of the fluid can be exerted on the entire exposed surface area of the sheet metal with the exception of that trailing portion of the sheet which extends toward the inlet gap and through which a portion of the fluid is permitted to escape.
  • roller means 16 (FIG. 7) which are urged outwardly away from the casing halves and toward the mandrel to thereby strengthen the force of application to the mandrel. It will be apparent that any suitable spring means 16 may be interposed between the roller means and its carrier means therefor which is associated with the casing elements.
  • the action of the fluid will be stopped when a sufficient number of layers have been formed around the mandrel, whereby complete adhesion of the sheet to the latter is ensured.
  • the casing surrounding the mandrel is in the form of two cylindrical half shells or elements 18 and 19 closed in a fluid-tight manner at its opposite ends by walls 14 and 15 (FIG. 6).
  • the cylindrical cavity of the expansible housing is coaxial with the mandrel 9 and its internal diameter is substantially larger than the external diameter of the mandrel.
  • the internal cavity communicates with the atmosphere through the longitudinally extending gap 3.
  • pivot pin which is common to the two half shell portions 18 and 19, which may be oscillated from their operative position at the end of the winding operation by being pivoted in the direction of the arrows 6 and 6a, as explained earlier herein.
  • the mandrel 9 is fixedly mounted on a hollow shaft 20 which is driven by means of a motor-driven gear reduction unit shown only generally at 12.
  • the hollow shaft 20 is closed in a fluid-tight manner at its outer end and is arranged to communicate through its other or inner end with an enclosed space, not shown, (see FIG. 6), in which there is provided a more or less high vacuum depending upon the particular characteristics of the sheet or strip to be wound.
  • longitudinally extending channels 21 which are situated at substantially regular intervals along the generatrices of a cylinder concentric with the mandrel, and the diameter of the base of which is slightly smaller than that of the mandrel itself.
  • the two end plates 14 and 15 close all the longitudinal channels 21 in a fluid-tight manner and are suitably perforated as shown in FIG. 6 to permit communication of conduits 22 and 23 (only two shown) with each of the channels 21 and the hollow shaft 20.
  • Radial orifices 17 extending from each of the longitudinal channels 21 lead to the surface of the mandrel and the pivot pins 1616 together with the supports 24 and 25 maintain the whole apparatus in an operative position.
  • the apparatus operates as follows: The negative pressure produced in the internal cavity of the hollow shaft 20 is transmitted through the conduits 22 and 23, as previously explained, to the longitudinal channels 21 and thereafter to the radial orifices 17 which are distributed over the entire surface of the mandrel.
  • the end of the sheet is engaged under the commencing second turn of the material about the surface on which it is then continuously wound to completion of the coil.
  • the vacuum is broken as soon as it is certain that the remainder of the sheet or strip to be wound can be driven without slipping since it henceforth adheres sufficiently to the mandrel.
  • an apparatus for forming a coil of strip material about a mandrel comprising, a separable housing arranged to surround said mandrel, said mandrel having an outer surface area, elongate means defining an opening in said housing permitting entry of a leading edge portion of a strip of material thereinto, means causing said leading edge portion to be brought into engagement with the outer surface of said mandrel, means for driving the mandrel to wind the strip into a coil thereupon, and means for separating the housing to permit removal of the coil.
  • the housing comprises substantially complementally formed separable elements.
  • the housing includes oppositely disposed end walls, said end -walls being provided with means adapted to provide closures for said housing.
  • said housing includes inner perforate wall portions, said housing being further associated with means furnishing a source of fluid under pressure which when emitted from said perforate wall portions causes the strip to be brought into surface contact with said mandrel.
  • the housing includes at least two substantially concave inner wall portions, said wall portions being complemental to the outer surface area of said mandrel.
