Abstract
Procédé et appareillage pour la réalisation de tiges en matière plastique pourvues de renflements espacés, dans lesquels la tige est soumise, aussitôt après son étirage, pendant que la tige continue son avance, à l'action d'une aspiration étant appliquée par intermittence dans des zones fixes relativement à la tige, de façon à déformer dans plusieurs points espacés entre eux, produisant une pluralité de renflements saillant latéralement, répartis à intervalles sur tout le développement de la tige. Applicable à la fabrication des tiges supports de plantes.
