Description of the Related Art Generally, in a lead-acid battery, an electrode plate in which a lead alloy substrate surface is filled with an active material is housed in a bag-shaped separator made of plastic such as microporous polyethylene, and the separator is used to form a battery case. The positive and negative electrode plates are isolated from each other, and an electrical short circuit between the positive and negative electrode plates due to the fall of the active material is prevented. A plurality of ribs are integrally formed on the inner surface of the separator so as to improve the diffusivity of the electrolytic solution and adjust the pressure applied to the electrode plate.

When accommodating the electrode plate in the separator, a sheet of plastic (microporous polyethylene) for a separator wound in a roll shape is sent to an envelope device,
While cutting the sent part to a predetermined length,
Fold it in half in a V shape and insert the electrode plate between them.
Moreover, the left and right ends of the sheet are joined by welding or mechanical pressure bonding to form a bag-shaped separator.

In recent years, a glass mat is often used in combination for pressurizing the active material and preventing oxidation of the separator. When this glass mat is used together, as shown in FIG. 10, a plastic sheet 1 for a separator and a glass mat 2 are superposed on each other to form a laminated body 3, and this laminated body 3 is used as a pair of drive rolls 4.
It is introduced between 5 and pinched, and these pair of drive rolls 4,
The laminated body 3 of the sheet 1 and the glass mat 2 is fed into the envelope device 6 by the rotation of 5.

A pair of drive rolls 4 and 5 which sandwich and feed the laminate 3 of the sheet 1 and the glass mat 2 are rolls having a flat surface with a metal or rubber lining and through which the drive rolls 4 and 5 are interposed. When the laminate 3 is supplied to the envelope device 6 by a constant length, the laminate 3 is cut into a constant length by the cutter 7. Then, the cut laminated body 3 is folded into two in a substantially V shape in the envelope device 6, the electrode plates are housed inside the laminated body 3, and the left and right ends of the sheet 1 in the folded laminated body 3 are welded or It is mechanically crimped and processed as a bag-shaped separator.
