Description

TAPE SLAB WITH TRIMMING SECTION, AND APPARATUS FOR ITS PRODUCTION AND INSTALLATION METHOD Field of the Invention This invention relates to slabs of carpets and, more specifically, to slabs of carpets with a section of trim that can be removed, a cutter assembly for making slabs of carpets, with sections of trim that can be removed, and a method to install these slabs of carpets with removable trim sections.

BACKGROUND OF THE INVENTION The carpet slab is usually manufactured by producing a long strip of slab material and then cutting square slabs from the strip. Identical slabs, installed side by side, provide an attractive carpeted floor surface, but sometimes uninteresting. As a result, enormous effort has been expended in producing slabs with patterns, which have variations in fur, color and other properties for aesthetic reasons. The dissimilar slabs have sometimes been installed in a checkerboard pattern or other patterns, and dissimilar slabs have been cut a few times and then reassembled, as suggested, for example, in U.S. Patent No. 5,324,562, for slabs of multi-segment carpets and methods and apparatuses for the production of said slabs. "Such prior efforts have very limited effectiveness or, as is the case with respect to the Patent No. 5,324,562, are expensive and internal labor for practice.

SUMMARY OF THE INVENTION This invention consists of a set of carpet tile cutters, a carpet slab and a method for installing this carpet slab. Said cutter assembly produces slabs of carpets with a discontinuous slit, which forms a section of trimming that can be removed, having a desired configuration, such as a square. This cutter assembly includes two sets of blades for cutting each slab and the discontinuous slit defining the cutting section. This section of trim is held in place by a bridge material formed by interruptions in the slot. The trim sections configured can be removed during installation, cutting the bridge material in the slit interruptions, and the trimmings can be replaced with each other or a quarter or half flipped in place to form a pattern on the cover of the slit. floor.

It is a primary object of this invention to provide a carpet slab cutting apparatus for making slabs of carpets with attached trim sections, but which can be removed. It is a further object of this invention to make a carpet slab with removable trim sections with an effective cost. Another object of this invention is to make slabs of carpets with attached, but easily removable, trim sections that are interchangeable. Still another object is to produce a carpet slab with a removable cut section, which can be manufactured and transported without incurring variable costs, in addition to the manufacturing cost of conventional slabs. A further object of this invention is to provide a method for installing a slab of slab with a removable trim section, to form a floor covering with a certain pattern. A further object of this invention is to manufacture a carpet cloth with removable trim sections, which can be installed without removing the trim section. Still other objects and advantages will become apparent from the following description, the accompanying drawings and the claims. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of an exemplary installation of slabs of carpets, according to this invention; Figure 2 is a schematic cross section of the mat, taken along lines 2-2 in Figure 1; Figure 3 is a perspective view of a composite cutter assembly of this invention; Figure 4A is a front elevational view of a portion of the cutter assembly shown in Figure 3, with the insert cutter and foot assembly spring loaded in the raised, decoupled position; and Figure 4B is a front elevation view of Figure 3, with the insert cutter and foot assembly in the lowered coupled position, to form the cutout section when the perimeter of the slab is cut.

Detailed Description of the Drawings Figure 1 shows an arrangement 8 of the slabs, 10 and 11, of carpets, cut by die, with cutting sections, 13 and 15, interchangeable, within the edge sections, 12 and 16. slabs, 10 and 11, in arrangement 8 are of two types. For example, the slabs 10 can have a high coat, while the slabs 11 have a smaller coat, or the slabs 10 and 11 can be of different colors. The slabs 10 and 11 are arranged in an alternative pattern. Each slab, 10 and 11, is manufactured with a central section, 13 and 15, defined by a cutting line 19, which has a shape generally closed, such as a square. The gaps in the cutting line 19 leave bridges 14 joining the cutting sections 13 and 15 to the edge sections, 12 and 16, respectively. The centers, 13 and 15, of interchangeable cut-outs 5 can be removed from their respective sections 12 and 16, by cutting the bridges 14 at the installation site, for example, with a service knife. The sections, 13 and 15, of trim are removed from their respective sections, 12 and 16, edge and are exchanged with other 0 sections, 12 and 16, edge respectively, to form a pattern. This pattern can be formed by varying many different aspects of the slab; for example, the color of the carpet, height of fur, chipping, orientation of the cutout or any other aesthetic aspect of the slab of general carpet. Figure 2 shows a cross-sectional view of slabs 10 and 11 of carpets with cut-out sections 13 exchanged or rotated. Each section, 13 and 15, of trim is removed from the slabs, 10 or 11, and placed on one edge, 16 and 12, dissimilar, respectively. Slabs 10 and 11 of tapestries can be manufactured and transported with the trimming section secured in place by the bridges 14. During installation, the installer can separate the bridges 13 with a service knife, remove the sections, 13 and 15, of cut and exchange them between tiles 10 and 11, or simply rotate them inside the edge, 12 and 16, of the tiles, from which they form a pattern. Alternatively, these slabs, 10 and 11, can be installed without removing the trim section. Conventional slabs of tapestry are typically cut from a web of material, with a reciprocal blade assembly, which cuts a group of loas from the web, retracts, so that the web can be advanced, and then cuts another group of slabs . These slabs 10 and 11, with the cutouts, 13 and 15, placed centrally, of the invention, can be produced by adding a set of blades to the conventional blade assembly to form the central cut-outs. Said blades for the cutouts can be fixed in relation to the blades of the perimeter of the slab, so that the cutting lines 19 of the cut-outs are always formed. Alternatively, as illustrated in Figures 3, 4A and 4B, the blades forming the cutout may be retractable for selective use. For illustrative purposes, Figure 3 shows the slab cutting apparatus, which operates in a band 60 with low height of the fur; however, the cutter 20 can be used in all types of bands. Figure 3 shows a slab cutting apparatus 20, which can be used to cut slabs 10 and 11 of carpets, from a band of the carpet slab material 60, which has a "direction of the machine ", indicated by arrow 61 in Figure 3. The slab-cutting apparatus 20 is connected to a fixed beam 22 by press cylinders 24 of the die assembly.These press cylinders 24 of the die assembly can be cylinders driven by air or hydraulically, but electro-mechanical and other impellers can be used to drive the assembly downwardly to engage the band 60 and above so the band 60 can be advanced.Thus, the slab-cutting apparatus 20 moves vertically relative to the fixed beam 22 and the band of the slab material 60The slab-cutter apparatus 20 includes fixed blades 55, which always engage the web 60 when the cylinders 24 are driven to cut the web of slab material on the slabs 11, along the slab separation lines 18 (shown in Figure 3). The cutter 20, illustrated schematically, includes an internal cutter assembly 40, which can be retracted, which makes the cutting lines 19. Each internal cutter assembly 40, which can be retracted, includes the blades 45 and foot assemblies 46, which can create the trim section 13 at the same time that the slab 11 is trimmed by the fixed blades 55. The internal cutter assembly 40 , retractable, can be operated by an air cylinder 27 or by other means, which include manual movement between the operating and retracted positions.

Unlike the external cutter assembly 50, the internal cutter assembly 40 is moved relative to the cutter slab cutter 20, and the outer cutter assembly 50. This up and down movement allows the internal cutter assembly 40 to be moved. between the coupled and uncoupled positions. This is advantageous because the carpet slab 11 can be made with or without an attached cutting section 13, depending on the position of the internal cutting assembly 40. Alternatively, the blades 45 can be fixed relative to the blades 55, as well that the cutting lines 19 always form at the same time as the slab 11 is cut from the web 60. In order to manufacture the slab 11, a strip of slab material 60 is fed under the slab cutting apparatus 20 . Once the band 60 is in position, the cutter apparatus 20 of the, moves downwardly in contact with the band 60. If the inner cutter assembly 40 is in the lower operative position, too much contact with the band 60 will create a line discontinuous cut 19, which defines the cutting section 13 and the bridges. If the inner cutter assembly 40 is in the disengaged raised position, a conventional carpet slab 11 will be formed without a cutout section 13.

Figures 4A and 4B show a simple cutter assembly 30 with an external cutter assembly 50 and an internal cutter assembly 40 disconnected and connected, respectively. The internal cutter assembly 40 includes multiple blades 45 mounted to a die plate 44. The blades 45 are attached to a foot 43 at the end of the arm 41, attached to the cylinder 27, which moves the blades 45 downwards to connect the band 60, as illustrated in Figure 4B, or upwards, disconnected, as shown in FIG. shows in Figure 4A. A standing plate 46, mounted to the die plate 44 by the rods 48 and the springs 47, applies pressure to the band 60 as the knives 45 cut the band 60, to facilitate a clean cut, placed exactly. The holes 42 in the leaves 45 leave the bridges 14 in the cutting lines 19. The outer cutter assembly 50 includes the blades 55 which are attached to a die plate 54 of the perimeter in an arrangement that forms the perimeter of the carpet slab 11. The standing plates 51 mounted on the rods 63, are forced against the band 60 by the springs 56 to exert pressure on the band, as the sheets 55 cut the carpet slab 11, to facilitate a clean cut, placed exactly. The perimeter die plate 54 is attached to the uprights 52. These uprights 52 are connected to the die frames 28 of the transverse perimeter Figure 1). The struts 52 secure the die 50 of the perimeter to the slab cutting apparatus 20. Since the slabs, 10 and 11, of tapestries can be manufactured with sections, 13 and 15, of trimmings attached in the same operation as the slabs 10 and 11 of the strip 60 are trimmed, the manufacture of the slabs, 10 and 11 , of tapestries, with the cuts, 13 and 15, incur without additional expense of the equipment expenses and do not require additional manufacturing stages or time, and no additional handling, since the cuts remain together. Since the carpets 10, 11 and 11 can be manufactured and transported with the attached cutting sections 13 and 15, installation flexibility is available. During installation, an installer can place slab, 10 or 11, of carpet as it was shipped or can remove sections, 13 and 15, of trimming, for example, with a service blade or other cutter, to cut bridges 14 Once the trim section 13 is removed, the installer can swap or rotate the trim sections, 13 and 15, between the installed edge sections, 12 and 16, to create a pattern. Many aesthetic features can be used to form the pattern in layout 8 of the slab of carpet (Figure 1). For example, the trim sections 13 and 15 can be formed in many configurations, which include circles, squares, triangles and an infinite variety of other configurations. In addition, the height of fur and headdress can vary to create a texture pattern. Also, the color of the carpet can be varied to form a color pattern. Any combination of the above examples or other attributes of the carpet slab can be combined to form a multi-configuration, multi-color texture pattern. The foregoing is provided for purposes of illustration, explanation and description of the embodiments of the present invention, which provides techniques and devices for the manufacture of lobes of carpets with removable trim sections and methods for installing these slabs to create a pattern. Modifications and adaptations to these modalities will be apparent to those skilled in the art and can be made without departing from the spirit of the invention or the scope of the following claims.
