Verfahren zum Flächendehnen von Lederstücken,1. Process for surface stretching of leather pieces, die zwischen zwei elastische Bänder eingelegt sind, mit welchen sie alternierend und zyklisch zwischen einem Satz von Vertiefungen und einem Satz von stiftförmigen Vorsprüngen bewegt und durch wiederholtes Eindringen der Vorsprünge in die gegenüberliegenden Vertiefungen gedehnt sind, dadurch gekennzeichnet,which are inserted between two elastic bands, with which they are moved alternately and cyclically between a set of recesses and a set of pin-shaped projections and are stretched by repeated penetration of the projections into the opposite recesses, characterized in that daß vor dem Beginn eines jeden Dehnungszyklus beide, die dehnbaren Bänder zusarrmen mit dem zu behandelnden Leder, gegenseitig zu s arrme ng ek larmier t sind, eins gegenüber dem anderen an peripheren Orten der Vertiefungen und, daß, bevor die elastischen Bänder sich anschließend bewegen, die Kl: arrme rung stets gelöst ist.that before the beginning of each stretching cycle, both the elastic bands connected to the leather to be treated are mutually clamped, one opposite the other at peripheral locations of the depressions and that before the elastic bands subsequently move, the clamping is always released. 2. Vorrichtung für die Ausführung des Verfahrens nach Anspruch 1,2. Device for carrying out the method according to claim 1, mit zwei dehnbaren Bändern, welche in einer Ebene bewegbar sind, die sich zwischen einem Satz von reckenden Vorsprüngen erstreckt, welche für eine reversierbare Verschiebebewegung in gegenüberliegende Vertiefungen hergerichtet sind, dadurch gekennzeichnet,with two stretchable bands which are movable in a plane extending between a set of stretching projections which are arranged for a reversible sliding movement into opposite recesses, characterized in that daß zwischen den reckenden Vorsprüngen (21) elastische Platten (22) und ihnen gegenüber an den Peripherienthat between the stretching projections (21) elastic plates (22) and opposite them at the peripheries e tf a « #e tf a « # der Vertiefungen (30) Kontaktoberflächen (3Ir) vorgesehen sind, welche parallel zur Ebene (p) der Bewegung der elastischen Bänder (4,5) angeordnet sind.the depressions (30) are provided with contact surfaces (3Ir) which are arranged parallel to the plane (p) of movement of the elastic bands (4,5). 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß die elastischen Platten (22) aus Lagen (22a, 22b) von elastisch em Ma ferial hergestellt s i &eegr; d .3. Device according to claim 2, characterized in that the elastic plates (22) are made of layers (22a, 22b) of elastic material. 4.
