Abstract

APPAREIL POUR L'ETIRAGE SUIVANT DEUX AXES DE FEUILLES DE MATIERE PLASTIQUE. DES TENDEURS COMPORTENT UN TAMBOUR RELIE A UN MECANISME A VIS SANS FIN ET A UNE ROUE A CHAINE ET SUR LEQUEL SE TROUVE UN ORGANE DE LIAISON ENROULABLE ET DEROULABLE FIXE AU TENDEUR VOISIN ET RELIANT LES TENDEURS POUR FORMER DES ORGANES DE TRACTION. LES ROUES LIEES AUX TAMBOURS PAR LE MECANISME SONT EN PRISE AVEC DES CHAINES D'ENTRAINEMENT. LA VITESSE DE DEROULEMENT DES ORGANES DES TAMBOURS CORRESPONDANT AU TAUX D'ETIRAGE ET A LA VITESSE DE LA FEUILLE EST REGLABLE DE FACON CONTINUE. APPLICATION A L'ETIRAGE DE FEUILLES DE MATIERE PLASTIQUE.APPARATUS FOR THE FOLLOWING TWO AXIS OF SHEETS OF PLASTIC MATERIAL. TENSIONERS INCLUDE A DRUM CONNECTED TO A Worm gear mechanism and to a chain wheel, on which there is a rewindable and unwinding linkage attached to the neighboring tensioner and connecting the tensioners to form traction units. THE WHEELS LINKED TO THE DRUMS BY THE MECHANISM ARE IN CONNECTION WITH THE DRIVE CHAINS. THE UNWINDING SPEED OF THE ORGANS OF THE DRUMS CORRESPONDING TO THE STRETCH RATE AND THE SHEET SPEED IS CONTINUOUSLY ADJUSTABLE. APPLICATION TO THE STRETCHING OF SHEETS OF PLASTIC MATERIAL.
