Patent

CA 2432032

A method and apparatus for continuously producing pasted positive and negative electrode plates (14, 12) from pasted lead or lead alloy expanded, punched or cast metal mesh strip (10) for use in lead-acid batteries without the use of paper barriers (22, 23). With a heated cutting devices, such as roll-mounted die-cutters (40) to a predetermined temperature range of at least about 150 ~C, preferably about 160 to 300 ~C, and more preferably about 180 to 210 ~C, eliminates sticking of the paste on the pasted metal mesh strip (10) to the cutting devices (42, 44) and obviates the need for the paper barriers (22, 23).

L'invention concerne un procédé et un appareil permettant de produire, de manière continue, des plaques électrodes positives et négatives collées à partir d'une grille métallique en plomb ou en alliage de plomb collée, déployée, perforée ou coulée, utilisée dans des batteries au plomb/acide sans avoir recours à des barrières de papier. Le chauffage de dispositifs de coupe tels que des coupeuses à l'emporte pièce montées sur un tambour à une température prédéterminée d'au moins environ 150 ·C, de préférence comprise entre 160 et 300 ·C, et idéalement comprise entre 180 et 210 ·C empêche le collage de la pâte se trouvant sur la grille métallique sur les dispositifs de coupe, et évite d'utiliser des barrières de papier.
