Definitions

  • the present invention relates to a membrane press.
  • the membrane press of the present invention is intended for use in applying a membrane to a substrate.
  • a particular example of the form of membrane with which the press can be used is formed of a flexible thermoplastics material which will soften when heated.
  • Membrane presses of the form to which the invention relates are used in the application of decorative coatings in the form of a membrane to work pieces.
  • the presses generally comprise a chamber which comprises a base and a closure which cooperates with the base and serves to sealingly close the chamber.
  • the work pieces which can comprise a panels such, as door panels, are located on the base with the closure open and a membrane is sealingly received across the base above the work piece.
  • the chamber is then closed.
  • the chamber is provided with a heating means which serves to heat and thus soften the membrane,
  • the chamber is also provided with a pressurisation means and the subsequent to the softening of the membrane a differential pressure is created within the chamber to each side of the membrane to cause it to be forced against the work piece to be in close intimate contact with the work piece.
  • Prior to the location of the work pieces within the chamber they are coated with an adhesive or alternatively the underside of the membrane is provided with a pressure sensitive adhesive whereby on the membrane being forced onto the work piece it is adhered thereto
  • Such presses generally generate significant differential pressures and in order to provide support for the base with closure in position it has been usual practice to locate the base and closure located within a press frame which serves to support the structure during the application of the pressure within the chamber.
  • the press frame of such prior art presses usually also has a lifting means for the closure and a locating system for the base where the base is typically movable from a position removed from the closure to a position underneath the closure.
  • the lifting means for the closure is usually a hydraulic press which holds the closure in position on the base whilst a differential pressure is applied to the membrane as described above.
  • the hydraulic press has needed to be very powerful, in order to hold to closure onto the base and in order to resist the pressures created within the space. Such powerful hydraulic presses are expensive and bulky.
  • One object of the present invention is to avoid the need for the substantial outer press frame of the prior art presses.
  • a further object is to avoid the necessity of the sliding base or any other tracking means therefor.
  • the present invention resides in a membrane press comprising an closure and a base, said base being configured provide an interior which is able to support a substrate to which a membrane is to be applied, the closure being movable between a closed position over the base at which it defines a closed sealed space between the closure and the base and an open position clear of the base to provide access to the interior of the base, whereby when in the closed position the membrane is supported between the closure and the base to define separate spaces above and below the membrane, said press further comprising a means to heat the membrane and to create a pressure differential to each side of the membrane, said base and closure having sufficient structural strength to be self supporting against the pressure differential created between the space and the exterior when in use, and locking means provided at spaced intervals around the junction between the closure and base to lockingly retain the closure in the closed position.
  • the locking means comprises a plurality of apertured lugs provided on the closure or the base and a correspondingly located set of pawl members on the base or closure respectively and adapted to engage the apertures in the lugs when in the locking position.
  • the pawl members are supported to one side of a pair of apertured members which will receive the respective lug between them when the closure is in the closed position said pawls being slidably receivable through the apertures in the lug and members when the closure is in the closed position.
  • the closure is pivotally supported to one side of the base.
  • the base is supported from a base structure and the closure is hingedly supported from the base structure.
  • the closure is pivotally supported from the base structure through a parallelogram linkage enabling the closure to be moved upwardly and laterally with respect to the base from the closed position to the open position.
  • the differential pressure to each side of the membrane has been effected by evacuating the side of the membrane adjacent the substrate. It has been found however that unless the substrate is porous or is formed with an array of apertures the surface of the substrate to which the membrane is to be applied carmot be very complex if the membrane is to closely conform to the configuration of the surface.
  • a positive pressure is applied to the face of the membrane remote from the substrate. This positive pressure has been applied by an inflatable bag accommodated in the closure into which oil or air can be introduced. Again this arrangement is limited in regard to the complexity of the surface to which the membrane can be applied.
  • the base is associated with an evacuation means for inducing a reduced pressure in the space and the closure is associated with a pressurising means for creating a positive pressure within the space when the closure is in the closed position.
  • heating of the membrane has been achieved by introducing a heated medium into the closed space. This has included using heated air which has been blown directly into the space or into the inflatable bag referred to above in order to provide both heat and pressure.
  • the difficulty with each of these arrangements has related to the limited control in regard to the degree of heating which is applied to the membrane and the thermal inertia of such a heating arrangement.
  • the closure is provided with the means for heating the membrane.
  • the heating means comprises a set of radiant heater elements mounted at spaced intervals within the closure and located such that they are directed onto the membrane when the membrane is in position in the space. It is a preferred feature that the space within the closure is provided with temperature sensors.
  • said base accommodates a support which extends across the base which is adapted to support one or more work pieces, said support being adapted to provide fluid flow to each side of the support when located within the space and said support being removable from the base.

  • the interior of the base 14 accomm ⁇ dates a perforated floor 60 which is spaced above the lower wall which is intended to support a substrate support 62 upon which one or more panels 64 may be positioned within the base 62 where the panels comprise the substrate to which the membrane is to be applied.
  • one or more panels are located on the substrate support 62 and a length of membrane 66 is laid over the base such that it is received over the upper edges of the base.

Abstract

Presse à membrane comportant un couvercle (12) et une base (14). La base (14) comprend une partie intérieure pouvant recevoir un substrat (64) sur lequel une membrane (66) doit être appliquée. Le couvercle (12) peut se mettre en position fermée sur la base (14), délimitant ainsi un espace hermétiquement clos entre le couvercle et la base. Il peut aussi se mettre en position ouverte, dégageant ainsi la base (14) à l'intérieur de laquelle on a alors accès. Lorsque le couvercle est en position fermée, la membrane (66) est soutenue entre le couvercle (12) et la base (14), délimitant ainsi des espaces distincts au-dessus et au-dessous de la membrane (66). La presse comprend aussi un dispositif (44, 48, 52) qui chauffe la membrane et crée une différence de pression de part et d'autre de celle-ci. La base (14) et le couvercle (12) sont suffisamment robustes pour être autoporteurs face à la différence de pression qui se crée entre l'espace clos et l'extérieur en cours de fonctionnement. Des éléments de verrouillage (22, 26, 32), répartis le long de la ligne de jonction entre le couvercle et la base, verrouillent le couvercle (12) en position fermée.
