Definitions

  • This invention has for its subject-matter a device for impressing raised patterns on sheet materials.
  • This raised pattern impressing technique is also referred to as embossing and is carried out on special calenders, called embossing calenders, which include inter alia embossing rollers carrying the raised patterns or designs to be impressed.
  • Embossing is of fundamental importance for the plastics industries involved in the manufacture of coverings and imitation hide, where the plastics are to acquire the surface appearance of leather or some specific hides or fabrics or other materials of various kinds.
  • plastics produced are intended for use in fashion articles, clothings, or accessories for articles of clothing, considerable variety and originality is required of the ornamental patterns in addition to quality embossing.
  • each sheet or web impressed with a new pattern or a new combination of patterns or designs requires, using conventional embossing techniques, the provision of a special embossing roller.
  • Each embossing roller is usually made of chromium-plated steel and has a length of about two meters, and requires high-precision engraving, which is cost-intensive and time consuming.
  • French Patent No. 2,107,707 shows a fully grooved roller structure from which shaped elements stand proud which are attached to the grooves. These shaped elements are removable and effective to produce the patterns for embossing.
  • German Patent No. 2,337,599 shows a number of spaced rollers successively active on one and the same sheet material. Each roller is engraved with part of the end pattern, and the final effect can be altered by just using some of the rollers or changing some rollers.
  • roller of said French patent can only be used for a specific and limited type of patterns: those carrying a motifs of limited spread, well apart from one another, it being impossible to emboss over the entire surface. For instance, the typical embossing for imitation hides is not feasible.
  • the device according to the cited German patent requires instead a complex and accurate embossing procedure for the pattern lapping.
  • all the rollers must be interrelated at all times, because they are to present decorations which can overlap one another at all times.
  • the technical task that underlies this invention is to provide a device which can substantially solve said technical problem.
  • a device for impressing raised patterns on sheet materials which comprises an embossing roller and an auxiliary roller lying adjacent for rotation about respective parallel rotation axes, said embossing roller presenting a cylindrical surface having surface corrugations adapted to impress raised patterns on said sheet materials, and is characterized in that said embossing roller comprises a plurality of consecutive assembly elements defining outwardly annular bands of said cylindrical surface formed with said surface corrugations and being aligned to one another along a longitudinal direction parallel to said axes of rotation, and that said embossing roller comprises means for releasably engaging said assembly elements effective to enable location of each said assembly elements at a selected location along said longitudinal direction.
  • the device of this invention is generally denoted by the numeral 1. It comprises an embossing roller 2, which may be made of chrome-plated steel, and an auxiliary roller 3, which may be made of a smooth elastic rubber, being arranged side-by-side and rotatably about respective axes 2a, 3a of rotation.
  • the embossing roller 2 has on the whole a cylindrical surface 4 carrying raised surface corrugations adapted to cause continuous raised stripes 5 extending between the rollers 3 and 4 to be embossed.
  • the stripes 5 may be any material, although paper would be embossed which, as suitably coated, will cooperate in defining the surface features of plastics imitating naturally occurring materials.
  • a first feature of the invention is that the embossing roller 2 is divided into plural assembly elements 8 arranged consecutively and aligned to one another along a longitudinal direction parallel to the axes 2a and 3a of rotation.
  • the assembly elements 8 each define outwardly an annular band of the cylindrical surface 4 which has respective surface corrugations for embossing purposes.
  • means 9, 10 of releasable engagement are provided for the assembly elements 8 which allow them to be each arranged removably at a selected position along said longitudinal direction.
  • the embossing roller 2 is provided with a supporting core 6 and a shroud 7 is provided on said core which itself defines the cylindrical surface 4.
  • the assembly elements 8 are defined by annular portions of the shroud 7 which are engaged removably on the core 6 and can be assembled together at mutually aligned positions.
  • the shroud 7 is defined by nine assembly elements or aligned annular portions 8 which are selected and positioned to impart on the ornamental patterns of the cylindrical surface 4, shown only schematically, symmetrical features about a transverse mid-plane to the embossing roller.
  • the number of positions of the assembly elements or annular portions 8 may be selected as desired, and particularly the structure of the shroud may even be quite asymmetrical.
  • the annular portions 8 differ from one another not only by their positions and specific markings but also by their longitudinal dimensions, in a parallel direction to said longitudinal direction of the embossing roller 2.
  • first thin marginal annular portions 8a For instance, in the illustrated case, first thin marginal annular portions 8a, second annular portions 8b of an intermediate size, and third annular portions 8c having largest longitudinal dimensions.
  • annular portions or assembly elements 8 have modular length dimensions measured parallel to the longitudinal direction of the embossing roller 2.
  • the length of the annular portions 8 is a multiple of a predetermined fraction of the length of the cylindrical surface. 4.
  • the second annular portions 8b are twice as long, and the third annular portions 8c are three times as long.
  • the releasable engagement means 9, 10 between the supporting core 6 and the annular portions 8 comprise discrete rotation-preventing elements 9 and translation-preventing elements 10.
  • the rotation-preventing elements 9 also form angular positioning members for the annular portions or assembly elements 8.
  • the rotation-preventing elements 9 comprise a longitudinal cutout 11 formed through the section of the core 6 which engages with the shroud 7, and correspondingly mating cutouts 12 formed in the annular portions 8.
  • the longitudinal cutout 11 is substantially round in cross-section and so are the mating cutouts 12.
  • Tab elements 13 are set astride between the longitudinal cutout 11 and the mating cutouts 12, as shown in Figure 7.
  • the mating cutouts 12 have limited length and are aligned on opposite sides from the annular portions 8. In that case, the tab elements 13 have limited length , do not slide along the longitudinal cutout 11, and are immediately positionable.
  • the translation-preventing elements 10 comprise a first fixed shoulder 14 located on one end of the shroud 7, and a second shoulder 15 which locates on the other end of the shroud 7 and is threadable over the supporting core 6 to clamp the annular portions 8 tight.
  • the diameters of the shoulders 14 and 15 are slightly smaller than the diameters of the annular portions 8.
  • the annular portions or assembly elements 8 have, as may be evinced from the foregoing discussion, a symmetrical structure about perpendicular mid-planes to the axis of rotation of the embossing roller 2, thereby they may be indifferently slipped over the core 6 at positions tilted through 180° from each other. In practice, it is impossible to change the side of the annular portions 8 facing the first fixed shoulder 14.
  • Figure 8 shows that the assembly elements or annular portions 8 have marginal regions 16 with interconnection surface corrugations, that is showing ornamental patterns which are effective to both separate and interconnect the surface corrugations of any directly adjacent assembly elements 8.
  • the device operates as follows.
  • any shroud 7 may be composed.
  • an embossing roller 1 may be set up which has a cylindrical surface 4 with ornamental patterns which are neatly divided into different regions, and with the most appropriate combinations and positions of the various regions, occasionally even in accordance with the products to be made.
  • ornamental patterns which are neatly divided into different regions, and with the most appropriate combinations and positions of the various regions, occasionally even in accordance with the products to be made.
  • the most appropriate combinations are selected as relates to pattern or material imitation, and then the annular portions or assembly elements 8 are positioned each time according to the size of the products to be made.
  • Figure 3 shows a handbag having a composite appearance, which is provided centrally with the pattern from the third annular portions 8c, whilst marginal regions are patterned according to the second annular portions 8b.
  • the width of the central region may vary considerably, and it may be best, therefore, to change the width of its respective pattern, such as by inserting on the shroud 7 individual third annular portions 8c, between the second annular portions 8b, or side-by-side pairs of third annular portions 8c, also between the second annular portions 8b. In the latter instance, the width of the pattern of the third annular portions 8c would be doubled.
  • the modular lengths of the annular portions 8 make any compositions of the shroud 7 simple and easy.
  • the edges may take specific markings, by exchanging the first annular portions 8a.
  • Combinatory figuring out confirm that such is the situation even when only some of all the rollers feasible are considered: e.g. those having their shrouds symmetrical about a transverse mid-plane and at all times only three different annular portions 8 at each half-length of the shroud. If one has thirty different types of assembly elements or annular portions 8 available, and two specimen per type, which are on the whole the equivalent of just ten embossing rollers of the traditional type, the invention allows formation of over twentyfour thousand different shrouds.
  • each annular portion 8 may be worth two if turned over.
  • annular portions carrying diagonal lines be considered for example: several annular portions laid side-by-side and in the same manner provide broad diagonal lines, whereas by alternating straight portions with turned-over portions one obtains a zig-zag or Greek fret motif.
