Definitions

  • the invention relates to a roller for scraping hair on the surface of felt semi-finished products.
  • the invention also relates to a device for scraping hair on the surface of felt semi-finished products equipped with this roller.
  • US 217,079 discloses a machine for shaving hats which comprises a plurality of knives on a revolving drum.
  • the aim of the invention is therefore to propose a roller for scraping hair on the surface of felt semi-finished products, which would eliminate the disadvantages of the background art by creating the roller as a machining product which would, however, imitate as accurately as possible the effect of the shark skin on a felt semi-finished product and thus it would achieve the same or at least comparable quality of scraping hair on the surface of felt semi-finished products.
  • the goal of the invention is achieved by a roller for scraping hair on the surface of felt semi-finished products, which contains a basic cylindrical body, whose principle consists in that on the outer circumference of the basic cylindrical body lamellas are mounted inclined to or perpendicularly to its surface, each lamella being provided on its outer side with scraping teeth with heads.
  • the heads of the scraping teeth of each lamella are shifted in the direction of the axis of the basic cylindrical body to the space between the heads of the scraping teeth of adjacent lamellas, and the heads of mutually closest scraping teeth of at least three successive lamellas are arranged outside a helix.
  • the scraping teeth are arranged approximately in a chessboard pattern, due to which using this roller results in high-quality scraping of hair on the surface of felt semi-finished products, which is comparable to scraping of hair on the surface of felt semi-finished products by a strip of shark skin.
  • the heads of the scraping teeth of each following lamella are shifted in the direction of the axis of the basic cylindrical body to the middle part of the space between the heads of the scraping teeth of the lamella, or directly into their geometric center.
  • the lamellas are mounted on the outer surface of the basic cylindrical body of the roller for scraping hair on the surface of felt semi-finished products perpendicularly towards this surface or inclined thereto at an angle of 45° to 65° towards the tangent at the point of the mounting.
  • these lamellas are mounted on the outer circumference of the basic cylindrical body with a pitch of 1.3 to 2.5 mm, whereby on some of its parts they can be mounted with different pitches, or they can be completely omitted.
  • the most advantageous variant of embodiment of a roller for scraping hair on the surface of felt semi-finished products according to the invention appears to be a variant in which the pitch between the heads of scraping teeth arranged next to each other ranges from 1 to 2 mm, the apex angle of the scraping teeth is from 15° to 60° and the height of the scraping teeth, or, to be more specific, the height of the scraping teeth protruding above the outer surface of the roller for scraping hair on the surface of felt semi-finished products is in the range from 0.3 to 2.5 mm.
  • the heads of the scraping teeth are partially ground off into the shape of a cylindrical area with a center on the axis of the basic cylindrical body of the roller for scraping hair on the surface of felt semi-finished products, while the radius of the cylindrical area is in the range from the highest and the lowest portion of the head of the scraping tooth.
  • the aim of the invention is further achieved by a device for scraping hair on the surface of felt semi-finished products equipped with this roller for scraping hair on the surface of felt semi-finished products.
  • Fig. 1 schematically represents a cross-section of a roller for scraping hair on the surface of felt semi-finished products according to the invention
  • Fig. 2 shows a detail of the mounting of the lamellas on the surface of the roller
  • Fig. 3 shows a detail of one lamella
  • Fig. 4 illustrates a detail of the scraping teeth of a lamella
  • Fig. 5 shows a perspective view of a part of two adjacent lamellas.
  • roller 1 for scraping hair on the surface of felt semi-finished products will be described with regard to Fig. 1 to Fig. 5 , which schematically represent one of the advantageous alternatives of its embodiment.
  • this roller 1 for scraping hair on the surface of felt semi-finished products, or one of its components is further modified by a number of various methods, which are, however, apparent to a person skilled in the art from the illustrated variant and the description below, and therefore not all of them will be explicitly described hereinafter.
  • the roller 1 for scraping hair on the surface of felt semi-finished products contains a basic cylindrical body 10 , on whose outer circumference are uniformly spaced grooves 2 .
  • these grooves 2 are parallel with the axis 11 of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products and are inclined towards its surface, or, to be more specific, towards the tangent at the point of the groove 2 .
  • all the grooves 2 may be arranged perpendicularly to the surface of the basic cylindrical body 10 , or, to be more specific, to the tangent at the point of the groove 2 .
  • these grooves 2 are then mounted lamellas 20 , which are provided on their outer side 21 , which protrudes above the surface of the basic cylindrical body 10 , with scraping teeth 22 with heads 23 , arranged next to each other, whereby these lamellas 20 are according to the arrangement of the grooves 2 arranged inclined to or perpendicular to the outer surface of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products.
  • the heads 23 of the scraping teeth 22 are preferably, although not necessarily, partially ground off into the shape of a cylindrical surface 230 with a center on the axis 11 of the basic cylindrical body 10 , whereby the radius of the cylindrical surface is in the range between the highest and lowest portion of the head 23 of the scraping tooth 22 (see Fig. 2 ).
  • This grinding off, or, to be more specific, the small areas created by it on the heads 23 of the scraping teeth 22 then prevents/prevent the scraping teeth 22 during scraping, when the roller 1 for scraping hair on the surface of felt semi-finished products rotates in the direction indicated in Fig.
  • the most significant feature of the roller 1 for scraping hair on the surface of felt semi-finished products according to the invention is the fact that the heads 23 of the scraping teeth 22 of each lamella 20 are shifted in the direction of the axis 11 of the basic cylindrical body 10 to the space between the heads 23 of the scraping teeth 22 of the adjacent lamellas 20 , and the heads 23 of mutually closest scraping teeth 22 of at least three lamellas 20 following one another are arranged outside a helix - see Fig. 5 .
  • the greatest advantage is the fact that the heads 23 of the scraping teeth 22 of each following lamella 20 are shifted in the direction of the axis 11 of the basic cylindrical body 10 to the middle part of the space between the heads 23 of the scraping teeth 22 of the preceding lamella 20 , or to the geometric center of this space. Thanks to this arrangement, the heads 23 of the scraping teeth 22 are mounted substantially in a chessboard pattern, and so they copy the spacing of the teeth, or, to be precise, the spines on the surface of the shark skin very accurately.
  • the lamellas 20 are mounted on the outer surface of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products preferably at an angle ⁇ , whose size is from 45° to 65°, to the tangent at the point of the mounting (see Fig. 2 ), whereby lower values are favorable for smoother, less intense and more gentle scraping; on the other hand, higher values are favorable for rougher, more intense scraping.
  • the size of the angle ⁇ to the tangent at the point of the mounting may be also different, e.g. even 90°.
  • some lamellas 20 may be mounted according to the requirements on the outer surface of the basic cylindrical body 10 at a different angle ⁇ to the tangent at the point of their mounting, than the other lamellas 20 , or, if necessary, some lamellas 20 may be mounted at any angle ⁇ , while others are mounted at a different angle ⁇ , or perpendicularly to the surface.
  • all the lamellas 20 are mounted uniformly on the entire outer circumference of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products with a pitch S (see Fig. 2 ), whose size is preferably in the range from 1.3 mm to 2.5 mm, depending on the width of the lamellas 2 .
  • a pitch S see Fig. 2
  • Lower values of the pitch S are advantageous for lower height of the scraping teeth 22 and for smoother scraping, whereas higher values of the pitch S are favorable for greater height of the scraping teeth 22 intended for pre-scraping.
  • the lamellas 20 on a part of the outer circumference of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products can be mounted with a different pitch S than on the remaining parts/parts of its circumference, or, in case of need, they can be completely omitted on a part of its circumference.
  • the lamellas 20 can be mounted on the outer circumference of the basic cylindrical body 10 obliquely with respect to its axis 11 (in respectively oriented grooves 2 ), whereby they form an acute angle with it, and/or in such a manner that only their scraping teeth 22 protrude from the grooves 2 by their full height or a part of it.
  • the size and shape of the scraping teeth 22 that influences the quality of scraping the most. According to the properties of the particular semi-finished product, it is advantageous to select the height v of the scraping teeth 22 , or, to be more specific, the height of the scraping teeth 22 protruding above the outer surface of the roller for scraping hair on the surface of felt semi-finished products ranging in size from 0.3 to 2.5 mm, and their apex angle ⁇ being in the range from 15° to 60° (see Fig. 4 ).
  • the pitch t between the heads 23 of the scraping teeth 22 of one lamella 20 which are arranged next to each other, are then selected preferably approximately in the range from 1 mm to 2 mm.
  • any of these parameters can be selected differently, according to the requirements, or according to the parameters of the semi-finished product being scraped and/or according to the requirements for the extent of scraping its hair on its surface. In general, it applies that lower values are favorable for final scraping, whereas higher values are favorable for pre-scraping.
  • the individual lamellas 20 are mounted displaceably on the outer circumference of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products.
  • this mounting is realized by two flanges 3 connected displaceably to the faces of the basic cylindrical body 10 of the roller 1 for scraping hair on the surface of felt semi-finished products and a shape coupling 31 formed in these flanges 3 and at both ends of each lamella 20 .
  • the mounting of the lamellas 20 can be realized by another known method, or by the shape coupling 31 of a different shape and/or arrangement than the one illustrated in Fig. 1 and Fig. 3 .
  • roller 1 for scraping hair on the surface of felt semi-finished products according to the invention is embedded in the existing device for scraping hair on the surface of felt semi-finished products without having to make any modifications or adaptations.
