Methods and a device for the continuous manufacturing of artificial muscle actuator device fibers are disclosed. The method includes: threading an untwisted fiber along the axis of a tube and inside the tube that includes a heating means to raise the localized temperature of a cross-section of the tube to a predetermined temperature; providing a tension on the untwisted fiber; and twisting the untwisted fiber while the fiber is within the tube.
摘要:
Die Erfindung betrifft eine Vorrichtung zum Temperieren eines laufenden Fadens mit mehreren im Fadenlauf hintereinander angeordneten Heizeinrichtungen. Eine erste Heizeinrichtung weist eine durch zumindest eine Gasflamme indirekt erwärmte Heizkammer auf, die sich zwischen einem Fadeneinlauf und einem Fadenauslauf erstreckt. Eine der ersten Heizeinrichtung nachgeordnete zweite Heizeinrichtung ist zur weiteren Temperierung des Fadens vorgesehen. Um möglichst eine Durchwärmung des Fadens mit vorbestimmter Fadentemperatur zu erhalten, weist die zweite Heizeinrichtung eine beheizte Fadenkontaktfläche auf, an welcher der Faden mit Kontakt führbar ist.
摘要:
Procédé et installation pour la fabrication d'un produit de fibre de verre dans lequel du verre fondu est transformé en produit de fibre de verre par les étapes de filage, étirage, ensimage et collection, suivi d'une étape de production du produit de fibre de verre ainsi obtenu étant ensuite soumis à un désensimage thermique, les fumées issues du four de fusion étant utilisées pour le préchauffage d'un réactif de combustion du four de fusion en deux étapes, une première étape dans laquelle de l'air est chauffé par échange thermique avec les fumées et une deuxième étape dans laquelle le réactif de combustion est préchauffé par échange thermique avec l'air chaud, l'air étant ensuite utilisé dans l'étape de désensimage du produit de fibre de verre.
摘要:
A stretching apparatus of fibre tows in a pressurized steam environment comprises a plurality of stretching chests (1) and associated supporting structures (3, 4, 6) arranged side by side, at the same level, on a holding frame. The stretching chests (1) are each formed by two opposed metallic half-chests (1b, 1t), delimiting a stretching chamber (2). The stretching chamber (2) has a generally rectangular section of a low height and opens outwards in correspondence of the two transversal edges of the stretching chest (1) through tow entry and exit openings. Inside the stretching chambers (2) the tows are treated with saturated or overheated steam at high temperature and pressure and simultaneously undergo a mechanical stretching operation. The half-chests (1b, 1t) are free to expand in the length direction within surrounding, rigid and pressure-resistant supporting structures (3, 4, 6) which precisely define the position of said stretching half-chests (1b, 1t) in the direction of their height. The half-chests are also mutually movable to cause opening and closing of each single stretching chest (1), independently from the others, for the insertion of the tows being processed, by means of an opening/closing mechanism of the upper half-chest (1t) with respect to the lower half-chest (1b).
