Abstract
In the heat treatment of leather, a piece of leather is
placed on a frame and attached thereto by a plurality of clips
so that the leather lies substantially flat on the frame. The
frame and the leather are subjected to heat treatment and
shape memory effect (SME) elements serve to apply stretch
ing forces to the piece of leather.
A suitable clip comprises a first part which is securable
to the frame, a second part which is movable relative to the
first part and grips the leather and an SME element which in
its transition range of temperatures displaces the second
part relative to the first part to stretch the leather.
