Definitions

  • the present invention relates to a gasket cutting device, particular reference being made hereinafter to rubber and/or plastic gaskets of the type applied to windows and/or door frames.
  • Gaskets of the stated type are currently made by extrusion in the form of cord-like or ribbon-like elements.
  • the extrusions are cut transversely to form a cord-like or ribbon-like structure provided with transverse cuts ( Figures 13 and 14); these cuts enable the gaskets to be easily folded around corners when the gaskets are installed.
  • gaskets without cuts and gaskets provided with transverse cuts have both to be stocked, with the costs and logistic difficulties which this involves.
  • the technical aim of the present invention is therefore to provide a gasket cutting device which eliminates the stated drawbacks of the known art.
  • an object of the invention is to provide a device which enables semi-finished gaskets (i.e. extrusions not provided with transverse cuts) to be adapted to any window and/or door frame independently of its dimensions, such that they provide an optimum seal.
  • Another object of the invention is to provide a device which simplifies the installation and logistics of gaskets of the stated type and limits the costs associated with their production and marketing.
  • the device of the invention enables the cuts to be made exclusively within the regions (corners) concerned.
  • the device 1 comprises a first and second element 2, 3 defining a seat 4 in which the gasket 5 to be cut can be positioned.
  • the first element 2 presents a plurality of blades 7 operable between a rest position (shown in Figure 1) and a working position in which the blades 7 project into the seat 4, so that when the gasket 5 is positioned in the seat 4, a plurality of cuts 9 are formed in the gasket 5 on operating the blades 7.
  • the cuts 9 are only partial in the sense that they do not completely separate the two portions on one and the other side of the cut 9 (in practice the two remain joined together) and are preferably transverse, but can also be oblique.
  • the blades 7 are all parallel and fixed to a support 11, itself fixed to a part 12 of the first element 2.
  • the part 12 and the support 11 each present at least two aligned through holes 13, 14; as can be seen in Figures 1 and 4, through each pair of aligned through holes there slidably passing a shaft 15 presenting an intermediate portion slidable through the holes 13, 14 and a first end fixed to a plate 17 facing the second element 3.
  • the opposite second end of the shafts 15 is enlarged to form a limit stop for the relative movement between the part 12 and the plate 17.
  • the plate 17 presents a plurality of apertures 20 traversed by the blades 7.
  • the holes 13, 14 and the shafts 15 are disposed in two parts of the device on opposite sides of a longitudinal axis 21 and of a transverse axis 22 through the device; in practice, this means that they are disposed in opposite corners about the axes 21, 22.
  • the device presents two springs 25 mounted about each of the two shafts 15; these facilitate return of the blades 7 into their rest position (shown in Figure 4) after each operation.
  • the second element 3 presents a plurality of slits 26 for receiving the blades 7 during cutting.
  • that surface of the second element against which the blades 7 strike is flat, continuous and covered by a layer of yieldable material such as nylon.
  • the device is provided with operating means which, in an embodiment, comprise a pincer arrangement on a structure supporting the first and second element.
  • the operating means comprise a hydraulic or pneumatic cylinder 28, preferably applied to the first element to translate the support 11; in this case the structure 29 to which the first and second element are fixed can be of any conformation and can be arranged to retain the plate 17 of the first element 2 and the second element 3 in a fixed relative position.
  • the gasket 5 is initially located with that part in which the cuts are to be made positioned in the seat 4 (as shown in Figure 2).
  • the device 1 is then operated (manually in the case of a pincer structure or by hydraulic or pneumatic operation if this is provided).
  • the part 12 and the support 11 (mutually rigid) slide along the shafts 15 and insert the blades 7 into the seat 4, with consequent (transverse partial) cutting of the gasket 5.
  • the cuts enable the gaskets to be applied with a very small radius of curvature (almost a right angle) and without the need to make cuts in any of that part of the gasket positioned along a straight line.
  • the gasket can then be removed from the seat 4 and installed.
  • the present invention also relates to a finishing process for gaskets to be installed on windows and the like.
  • the process consists of partially cutting the gaskets, preferably transversely, during installation in those portions which are to be positioned at the corners of the windows or door frames.
  • the device of the invention is particularly advantageous as it limits the quantity of gaskets to be purchased and stocked (in the case of wholesalers) or to load onto the assembly line (in the case of window or door manufacturers), so limiting overall costs.
