Ces formes sont trempées dans le-bain d'élastomère et, une fois séchée la couche - plus ou moins épaisse suivant la destination de l'objet, notamment du gant - que l'on veut obtenir, recouvrant la forme, These forms are soaked in the elastomer bath and, once the layer - more or less thick depending on the destination of the object, in particular the glove - is dried, which we want to obtain, covering the form,
l'objet formé est démoulé.the formed object is removed from the mold.

Ces opérations sont casing of the form for the purpose of either introducing air or water so that, under the effect of the pressure, the object is ejected from the form, or to grasp, manually or mechanically, the film to strip the object of the form by inversion, which is the case for a flocked glove (a right shape produces a left glove). These operations are
difficiles et nécessitent généralement une intervention manuelle. difficult and usually require manual intervention.
La présente invention apporte, au problème du démoulage, en particulier du démoulage par retournement, des objets obtenus sur The present invention brings, to the problem of demolding, in particular of demolding by turning, objects obtained on
