Definitions
- the present invention relates generally to target faces as used in a number of projectile sports, especially toxopholy and small arms shooting for sporting purposes.
- Known targets for such sporting purposes in the case of toxopholy (more commonly known as archery) comprise a body of impact-absorbing material, conventionally known as a butt, to the front face of which is attached a removable target face printed with the target indicia usually (but not exclusively) conventional concentric circles.
- the butt is normally formed of straw or polymer foam and can be re-used many times.
- target faces suffer puncture damage and, of course, for competitive use, it is necessary to maintain a clear distinction between the entry points and therefore scores attributable to different competitors.
- Target faces are, therefore, readily removable and usually held to the front face of the butt by special pins.
- Prior art archery target faces intended to be positioned on the front face of a butt, are formed of paper which is frequently laminated for example with an open polyamide mesh reinforcement having a mesh size of about 10mm. This reinforcement is primarily intended to prevent stretching or deformation of the target face which would cause changes in the shape and dimensions of the printed target indicia.
- Known paper target faces have a major disadvantage, however, in that they are not waterproof and this causes considerable problems in outdoor use, especially since many archery competitions take place out of doors. It is always inconvenient to have to discontinue a competition due to inclement weather and, of course, the disadvantage this places on competitors competing at the time is considerable.
- a removal target face can be listed as follows: first it must be tough durable and stable when exposed to ultraviolet radiation, yet be easily puncturable when struck by the intended projectile. It must also be capable of receiving indicia with well-defined edges to define the target area, and it must be completely stable, that is it must not be subject to any dimensional changes when experiencing variations in humidity or moisture. In particular, it must not swell upon being saturated nor shrink upon drying nor must it loose its structural integrity in either situation; moreover, it must not stretch or shrink within the range of working temperatures normally experienced, regardless of any humidity and/or moisture changes.
- the target image should have a non-reflective matt surface and, of course, because it is a consumable item it must not be too expensive.
- plastic sheeting although suitably puncturable and water proof, and although it can be printed, fails to match up to the requirements in several other respects, in particular, such material, especially polyvinyl chloride (PVC) shrinks and stretches with changes in temperature, and can crack under certain conditions; moreover, when used as an archery target, it has been found that arrows tend to pick up material from the target face on penetration, and when printed it tends to be too reflective.
- PVC polyvinyl chloride
- a lamina element for use as a target face characterised in that it at least substantially comprises a piercable layer composed of a mesh of polymer fibres substantially non-deformable in the plane of the layer, bearing target indicia of water-resistant ink or dye.
- HDPE high-density polyethylene
- the mesh of the piercable layer preferably comprises a non- woven polymer fibre layer. This may be presented as a substantially homogeneous single layer on which the target indicia are marked by printing or dyeing, or the layer may be part of a composite structure which will be described in more detail below.
- the selection of polymer fibre material and the ink or dye is such that the ink or dye impregnates the said non- woven material upon application, that it the ink or dye stains the fibres themselves rather than overlying the surface formed by the mesh.
- the present invention also comprehends the application techniques which will be described in more detail below.
- the said layer of non- woven polymer fibres may be rendered substantially non- deformable in the plane of the layer by treatment or by composition with an adjacent layer. It may, of course, be inherently non-deformable as a consequence of the production technique.
- the printed or dyed surface of the said layer is preferably a substantially non- reflective or matt surface. This is achieved by a suitable choice of inks or dyes for formation of the target indicia as will be described below.
- the said ink or dye of which the target indicia are formed is preferably a water- based material.
- the said layer is composed of a material not susceptible to shrinkage upon contact with water, upon drying out or upon exposure to solar radiation.
- the said layer is at lest partly composed of TYVEK non- woven sheet material which is a non- woven flexible material made from HDPE fibres which are spun, randomly deposited and bonded by compression to produce a uniform layer about 0.19 mm thick with a density of about 60 gsm. This material has a non-reflective matt white surface on which target indicia can be printed.
- the said layer may, as mentioned above, be entirely composed of this material or may be partly composed thereof or of carbon fibre or KEVLAR (RTM) or carbon fibre mesh.
- the thickness of the said layer lies in the range 0.1 mm to 0.6 mm, preferably in the region of 0. 2 mm.
- the density of the said layer preferably lies in the region of 30 gsm to 200 gsm, preferably between 50gsm and 70 gsm.
- a specific embodiment has a density of 60 gsm.
- Reinforcement of the said layer may be achieved by use of a backing layer of another material, preferably also in the form of a mesh of fibres.
- the material of the present invention may have a layer of adhesive on one surface of the said layer to allow it to be secured to a butt by this adhesive.
- Suitable adhesives include pressure-sensitive low-tack materials.
- the present invention also comprehends a method of producing a target face comprising the steps of forming a web composed of a mesh of polymer fibres, applying a plurality of target indicia to one face of the web by printing or dyeing, and separating individual target faces from the web between adjacent target indicia.
- the target indicia are preferably applied to the web by flexographic or gravure printing, screen printing or web offset printing techniques.
- the inks utilised for these printing techniques are preferably water based inks having low-reflection properties and a degree of elasticity when dry (selected by choosing an appropriate polymer content) as to be sufficiently elastic to allow flexing of the target when being handled, and of impregnating the material.
- the method of the invention may also further comprise the step of perforating the web between adjacent target indicia and storing the thus-perforated web on a roll prior to separation of individual target faces therefrom.
- This allows a plurality of targets to be delivered for a competition on a roll, permitting convenient and easy storage and transport, and for the competition authorities to remove targets one at a time from the role for use.
- the targets may be individually numbered upon removal, or the printing technique may apply an identification number to each target. This assists in correlating the competitors with the targets.
- Each individual target face may be substantially rectangular, with circular indicia printed thereon, or the separation of individual target faces may remove from the web a circular element the size of which corresponds substantially (or slightly less than) the diameter of the butt to which the target face is intended to be attached in use.
- Figure 1 is a perspective view of an archery butt showing a target face of the invention in position ready to be secured thereto;
- Figure 2 is a schematic diagram illustrating one embodiment of the method of the invention for forming target faces.
- FIG. 1 there is shown an archery butt generally indicated 11 of otherwise conventional form comprising a circular body 12 of compressed straw borne on tripod legs 13, 14 and 15.
- the front face of the butt 12 is covered with a target face 16 formed in accordance with the principles of the present invention and this can be secured in place by conventional face pins 17 shown only schematically in Figure 1.
- the target face 16 is composed of a single sheet of TYVEK (a registered trademark of Dupont) which is a non- woven flexible material made from HDPE fibres which are spun, randomly deposited and bonded together by compression to produce a uniform thickness sheet of about 0.1 mm having a density of about 60 gsm.
- TYVEK a registered trademark of Dupont
- the random deposition of the fibres and their bonding together results in the ability of the material to resist deformation within the plane of the layer in all directions. Because it is not a woven mesh there is no preferential direction of stiffness and no risk of stretching on a diagonal or bias line as there would be with a woven mesh.
- the target face 16 is cut to a circular shape to match that of the butt 12, with the pin 517 being positioned at suitable intervals around the periphery.
- a target face could be cut from a square or rectangular sheet of material (albeit printed with a circular target image) and the corners folded over the butt to be secured in position by pins fitted to the edge region or the rear face of the butt depending on how far around the corners of the target face pass when the target face is being fitted to the front of the butt.
- FIG. 2 illustrates the major steps in the production of a target face in accordance with the principles of the present invention.
- the block 18 represents the formation of the fibres which are then passed between guide rolls 19, 20 which directs them towards a heating station 21 at which the fibres are raised to a temperature at which they will bond together upon compression.
- the roving thus formed and heated is passed between two compression rolls 23, 24 at which the fibres are bonded together to form a stable web 22 which is then rolled onto a storage roll 25.
- Sheets of TYVEK non- woven sheet material have a non-reflective matt white surface which, when printed with suitable water-based flexible inks will have a matt non-reflective image.
- the material is extremely strong and tear-resistant but can be penetrated by arrows without difficulty, the arrows penetrating between the fibres and causing displacement of these without rupture of any material and without pick up of material from the target face.
- the nature of the material is highly weather proof. It is not affected by contact with water and does not stretch or shrink over a wide range of temperatures.
- a target face for use in pistol or riffle shooting may be formed from a matt white sheet of TYVEK non- woven sheet material having a slightly greater weight than the previous embodiment, say about 80 gsm, again comprising a single sheet of TYVEK non- woven sheet material.
- Such a sheet may be held in a frame without an adjacent backing, in front of a suitable absorbent material such as a sand bank or a wall of sandbags, such that projectiles having passed through the target are stopped in a conventional manner. Again, penetration of such a target face by a projectile does not result in tearing or rupture of the material, but rather lateral displacement of the fibres leaving a neat round hole accurately representing the point of impact of the projectile.
