DESCRIPTION OF THE INDUSTRIAL INVENTION ENTITLED: "MACHINE FOR THE PRODUCTION OF SCALED SKIN SIMILAR TO THAT OF REPTILES AND FISH AND RELATED PRODUCT OBTAINED"

SUMMARY

The subject of the present patent for industrial invention is a machine and the product deriving from it, i.e. the machine produces on normal animal skins, both gold and finished, inclined notches with respect to the flower or surface, against an adequate contrast, generally wavy, such to lift a portion of the epidermis very similar to the scales of the skin of snakes or fish. Then, by operating these carvings in succession, against contrasts, equal in shape, but offset, the resulting scaling is also alternated just like in the hair of reptiles and fish. The product, therefore, is a scaly hair with parallel lines but with offset (or misaligned) intaqli such as to reproduce the scaling of the real skins of reptiles and fish. Considering that these skins are subsequently appropriately stained with suitable paints, it is understood that the final product offers an almost total resemblance to natural snakes and fish skins.

The use of these leathers is obviously intended for footwear, for the production of suitcases and leather goods in aenere.

DESCRIPTION

The attached tables 1 and 2 show both the machine and the various mechanisms making up the same, while table n. 3 and in the relative fipure the final product deriving from the processing carried out on the leather is refined. Moving on to a careful examination of the tables and figures, the various essential components can be deduced.

support 9 suitably grooved in the direction of travel of the leather - 2 - while the cylinders - 4 - stop, The aforementioned device - 8 - acts with two elements - 5 - and - 7 - as a blank holder towards the skin - 2 moreover the two stop elements - 5 - and - 7 - are integral with each other - being connected to the ends from the plates - 6 -. Once the skin - 2 - has been stopped against the grooved support - 9 - (which we will discuss in detail in the description of table, n, 2) the blade - 10 - is pushed into the guide - 11 - by the feed device - 12 - , also equipped with the same type of movement of the device - B - that is, hydraulic or pneumatic or mechanical (as in the figure but purely indicative), quickly against the leather to produce superficial incisions very inclined with respect to the contrast plane. These incisions, due to the underlying profile - 9 -, grooved, are almost trianolar in shape due to the rise of the groove. The blade - 10 - after the incision, retracts upwards and the pressing device - 8 - draws the two pressing elements - 5 - and - 7 - also upwards, which free the skin again 2 in such a way that the cylinders 4 can make it advance by a predetermined step in the direction of the arrows - 3 -. At the end of the advance, a new cycle resumes. this first station by means of - Θ - first and - 12 - then. As soon as the skin reaches the second station physically identical to the first, a second inclined incision will begin, but this time offset by half a step with respect to the first and with the grooved plane - 19 - also arranged with its grooves transversely shifted by half a step. . The result, therefore, on the skin - 2 - will now be a series of incisions identical to the previous ones but staggered with respect to the first half steps both in second advancement - 3 - and transversely. In table 1 at n. - 18 - a device identical in all respects to - 8 - is indicated, two pressing plates - 15 - and - 17 - identical to - 5 - to - 7 - connected to each other at the ends by plates - 16 -. Even the aruppo carrying the blade - 20 - sliding in the guides - 21 - and moved by the mechanism - 22 - is completely identical to that made up of - 10 -, - 11 -, and - 12 -. The plane - 19 - is also geometrically identical to the plane - 9 but arranged transversely shifted by half a step with respect to the grooves of 9 and as better shown later. Proceeding in this way with an advance and a linear series of engravings on the first, a second linear series of engravings will be obtained at the same time. also on the second station. but. as mentioned, offset by half a step both longitudinally, arrows - 3 -, and transversally. The skin - 2 - at the end of the passage and of the various incisions will thus present an appearance very similar to the scaling of natural snake or fish skins. In table no. 2 in fig. 1, not restrictive - three types of support planes - 9 - and - 19 - are shown, which offer contrast to the skin - 2 - only in the highest part of their profile during the incision of the relative blades - 10 - and - 20 -. In this fiaure it is also highlighted with the hatching that the profile - 19 - on the machine is in any case offset by half a step with respect to the profile - 9 -. In the same fig. 1 furthermore, the three drawn profiles show only some of the possible traces that can be created on the contrasting planes - 9 - and - 19 these grooved profiles on a block, or roller, of a generally metallic nature, produce wider or narrower notches depending on their end which obviously offers more or less contrast to the blade that engraves the leather - 2 -, Finally the fia. 1, above clearly shows that several profiles can coexist on the same plane or roller - 9 - and - 19 - producing more or less marked incisions on the same line. Turning to the examination of figure 2 of table no. 2 it is possible to detect a double incision station in which a single locking device - 8 - stops the leather - 2 - with respect to the two supports - 9 - and - 19 - grooved with the two locking elements - 5 - and - 7 - integral with two side plates - 6 -. In this compact version, the two blades - 10 - and - 20 - descend together driven by the mechanism - 12 -, completely identical to the one mentioned in the single stations. Both in the case of single and double stations, the blades can in any case be mounted and adjusted with different pitch inclinations depending on the matrices it supports - 9 - and - 19 and to obtain more or less superficial incisions in relation to the type of reptile or fish skin that you want to imitate. In table no. 3 in fiq. 3 shows a generic schematic which indicates the effect produced by the blades - 10 and - 20 - on the leather - 2 In fact, the arrow - 3 - indicates the advancement mode of the leather - 2 -, advancement in predetermined steps, shows q the elements - 5 - and - 7 - for locking the skin and the blades - 10 - and - 20 - which cut and come out according to the arrows - 13 - while under the skin there are the contrasts - 9 - and - 19 - as described in the previous figure 1. The blade - 10 -, in figure 3, produces the incision of the epidermis - 14 - of figures 4 and 5, while the blade - 20 - produces the incisions - 24 - in the middle of the incisions - 14 - and also staggered transversely there is half pitch of the grooves of the plane 19 with respect to. floor 9 These -facts are further highlighted by -figures 6 and 7, in the first, in fact, a section of the leather already engraved is depicted where with - p10 - the incision steps of the blade are indicated - 10 - and with - p20 - those of the blade - 20 -, In the second, fig. 7, on the other hand, shows a top view of the leather - 2 - engraved, where the incisions - 14 - are produced by the blade - 10 - with contrast - 9 - and the incisions - 24 - are produced, staggered, by the blade - 20 - with contrast - 19 -. Obvious result. of this type of processing is a skin with the epidermis presenting roughly triangular flaking that make it completely similar to a reptile or fish skin. Furthermore, by thickening or widening the transversal and longitudinal incision steps with the variations of the various contrasts - 9 - and - 19 - it is possible to obtain an almost infinite range of skins similar to those of reptiles in general and of fish in particular.
