Abstract
A method and an apparatus for expanding a preslit deformable mesh sheet and an improved battery grid are disclosed. The method comprises the steps of positioning the lateral edges of the deformable strip with the same horizontal plane; laterally expanding the preslit portion of the strip while maintaining the lateral edges within the said horizontal plane; and vertically expanding the preslit portion of the strip selectively and concurrently with the lateral expansion thereof while maintaining the lateral edges in the horizontal plane. The apparatus comprises means for diverting one lateral edge from the other and laterally expanding the preslit portion of the deformable strip, while maintaining the lateral edges within the same horizontal plane, and means for vertically expanding the preslit portion of the deformable strip selectively and concurrently with the lateral expansion. The resultant grid embodies a degree of uniform expansion in a grid having varied interstices which is not found in the prior art grids.
