A manufacturing process of three-dimensional leather objects, including the following steps: applying a hardener additive on the flesh side of a piece of leather, positioning the flesh side of the piece of leather on a shape, introducing the shape with the piece of leather in a vacuum sack, applying rough vacuum in the vacuum sack, heating the vacuum sack with the shape and the piece of leather, and progressively applying vacuum during the heating step, stopping the vacuum pressure and cooling the vacuum sack with the shape and the piece of leather, opening the sack and extracting the shape with the piece of leather from the vacuum sack and removing the piece of leather from the shape in such a way that the piece of leather has the shape of a three-dimensional object.

A covering material (1) includes an outer layer (2) made of natural leather, a resin foam layer (3) adhered to a back surface of the outer layer (2), and a lining layer (4) provided on a back surface of the resin foam layer (3). In the lining layer (4), slits (5) are formed.

A process for forming a seam construction on a substrate includes steps of: a) providing a first thread coated with a first curable resinous material; b) providing a second thread coated with a second curable resinous material; c) forming a stitch knot; and d) curing the stitch knot to chemically bond the first and second curable resinous materials together.

A method of manufacturing a phylactery, the method including providing an initial stage phylactery workpiece formed of animal skin, cutting the initial stage phylactery workpiece to define a second stage phylactery workpiece, the cutting including forming at least outline cut lines, interior cut lines and incised lines, and folding the second stage phylactery workpiece along at least some of the incised lines to define the phylactery.

A method for producing a covered steering wheel for a vehicle. A steering wheel skeleton is overmolded with a matrix material. A covering material is coated on its non-visible side with an activatable material. The coated covering material is applied to the overmolded steering wheel skeleton so that its non-visible side faces the overmolded steering wheel skeleton. Longitudinal edges of the covering material are joined together. The activatable material is activated with creation of an integral connection between the covering material and the matrix material.

A manufacturing process of a leather eyeglasses frame and eyeglasses frame obtained with such a process is disclosed. An eyeglasses frame is provided wherein the frontal lens-holder frame, and possibly each of the two lateral temples, are made of two identical layers of leather, between which a thin reinforcing metal core is concealingly inserted.

Riding saddle having a two-stage, additionally elastic girth for fastening on a horse. Due to the two-stage, preferably elastic girthing, the riding saddle has the advantage of a firm fit on the horse's back. It has shown that due to the girthing according to the invention, an otherwise identical saddle slides forward significantly less on the horse during riding.
