A Tannery System (DT), for providing a Batch (LOkr) of Hides (1ij) with a homogeneous Grade (Gkr) from multiple Tanneries (Fi), intended to undergo a Transformation Stage (Se); (i) whose size is greater than the number of Hides having a Grade (Gkr) of each Tannery; and (j) that minimizes or maximizes the statistical numeric Constraint Parameter (PN) of a global statistical technical characteristic of all Hides in the Batch. It includes (a) a Computer Network (RL) that connects an online Platform (CL) to at least two Tanneries and their two Digitizing Scanners (19i); (b) Means for Filtering (25) by the Grade (G) all the Hides (1ij) available, to select the Combined-Subset (SCkr) of the Complying Fractions (FCi) of Hides from the Tanneries having the Grade (Gkr); (c) Means of Batch Optimization (26) for (i) performing Selections of Collections of combined Complying Sub-Fractions (Sim) of Complying Fractions, (ii) for determining for each Selection, the reached value of the Numerical-constraint Parameter, and, (iii) for constituting the optimal Batch by the Selection which maximizes or minimizes the Numerical Constraint Parameter.

A method for marking references on a flat article includes providing a model having at least a through-opening and exhibiting the same peripheral profile as a flat article to be marked; detecting the peripheral profile of the model and storing that profile in a memory; detecting a profile of the through-opening and the relative positioning with respect to a reference system; detecting a peripheral profile of the flat article; replicating the peripheral profile of the model so as to superpose it on the peripheral profile of the flat article; replicating also the profile of the through-opening of the detected model, taking account of the relative positioning with respect to the reference system and of the positioning of the peripheral profile of the model with respect to the peripheral profile of the flat article. Contactless marking of at least a reference on the flat article is made at the profile of the through-opening which has been replicated.

The present invention discloses a kind of production process for a fully covered leather sheath product, which comprises the following steps of: determining peripheral dimensions of leather such as the length and width according to the size of the product, and coating the leather with an adhesive; putting the shell of a product to be covered into the upper die of a mold, placing the trimmed leather into the lower die of the mold, and positioning it by a positioning post; heating the above-mentioned leather placed in the lower die of the mold; closing the upper die and the lower die immediately after the heating treatment is complete; opening the mold until the lamination is complete, taking out the product from the mold and fitting it with a fixture for the stretching folding treatment; heating the product along with the fixture to bond the leather with the interior of the product shell; and pressing it along with the fixture after heating; taking the pressed product out of the fixture and cutting excessive leather, attaching an inner lining material of the same dimensions after the excessive leather is cut, and pressing the inner lining material for bonding. The objective of the present invention is to provide a production process for the fully covered leather sheath product, which has high production efficiency and can improve the overall product design effect.
