Abstract

A three-dimensional mapping machine for leather or similar material covered objects comprises a support defining a working volume for housing an object and scanning means connected to the support and suitable to define a line of sight towards an area to be mapped onto the object itself; the mapping machine further comprises dynamic variation means of the arrangement and/or the relative position between the covered object to be mapped and the scanning means.

Abstract

The object of this invention is an apparatus (1) for detecting defects in at least one portion of leather, and for cutting the portion, that permits to perform faster and more efficiently than with currently known systems the operations of dilating, moving and cutting said at least one portion of leather, by supporting the leather on a curved surface that is extendible and rotatable around an axis in a monitored zone by suitable display means.

Abstract

A machine for automatic detection of flaws on pieces made of leather or similar material comprises a support element adapted to receive at least one piece of leather, scanning means adapted to detect an image of a first face of the piece and to convert it into an analysable signal, and processing means adapted to process the analysable signal and to identify at least one anomaly that can be correlated with a portion of the first face of the piece; the machine further comprises supporting and centring means to be activated on a second face of the piece, opposite to the first face, and adapted to determine localised tensioning of the piece at least at a scanning line optically aligned with the scanning means.
