The invention relates to methods and devices for shaping plastic optical fibres(POFs), more specifically for optically modifying and yet more specifically for rapidly joining two portions of the plastic optical fibres to create a new optical connection. The plastic optical fibres (1) may be heated under controlled conditions, to soften them and lens, sensor or patterns (7) may be imprinted on portions (8) of the fibre. Methods are provide to optical joints, and combined physical and optical joints.
摘要:
A fiber cushion body (1), which is formed from cross-linked fiber material and which is resiliency deformable when load is applied along a main load direction (2), is treated using ultrasonic energy. A portion (21) of the fiber cushion body (1) is displaced, for example using a sonotrode (20), and ultrasonic vibrations are applied to the fiber cushion body (1) to re-shape the fiber cushion body (1) from a first shape to a second shape different from the first shape.

摘要:
A manufacturing method of an insulation cap (1), includes the steps of : supplying an elongated tube (11) from a tube supplying unit (20) to a tube placing table (33); moving a tube press-fastening portion (35) and a welding body portion (40) towards the tube placing table so as to press-fasten a press-fastening position of the tube placed on the tube placing table and t press-contact a press-contacting position of the tube placed on the tube placing table; performing a welding process with respect to the press-contacting position of the tube; moving the tube placing table during the welding process to feed the tube in a tube feeding direction by a specified amount; blanking the tube subjected to the welding process after feeding the tube to form the insulation cap; and discharging the formed insulation cap from a blanking position.
摘要:
La présente invention se rapporte à un procédé de jonction entre un premier panneau acoustique (2) possédant une structure alvéolaire de type nid d'abeille et un deuxième panneau (2'), comprenant les étapes visant à : - introduire au moins un mandrin (5, 8) possédant une forme adaptée aux alvéoles (3) dans au moins une alvéole (3) située à proximité d'un bord de jonction (6) du panneau acoustique, - passer sur ledit bord de jonction du panneau acoustique un galet (12), - joindre ensemble le bord de jonction du panneau acoustique avec un bord de jonction (6') du deuxième panneau et les solidariser par application d'un moyen de liaison.
摘要:
A telecommunications cable includes a distribution cable, a tether branching from the distribution cable at a breakout location, and an enclosure that surrounds the breakout location. The enclosure is secured to the distribution cable at first and second adhesion regions. The enclosure can also secure to the tether at a third adhesion region. The adhesion regions are treated by sanding the regions, cleaning the regions, and then plasma-etching the regions immediately before welding/injection molding the enclosure around the breakout location.
摘要:
An end (1a) of a pipe (1) made of a plastic material that has memory properties is connected onto an end (2a) of a connecting piece (2). The wall thickness of the pipe end (1a) is temporarily decreased. Thereafter the end (1a) of the pipe (1) is positioned on the nipple end (2a) of the connecting piece (2). The wall thickness of the end (1a) of the pipe (1) is returned towards its original size such that the pipe (1) firmly and sealingly presses against the connecting piece (2).
摘要:
