The orifice plate has an opening through which battery paste material is dispensed out of a hopper. The support structure underlies a battery plate grid strip and supports the battery plate grid strip upstream of the opening. The belt traverses beneath the orifice plate and carries the battery plate grid strip downstream of the opening and downstream of the support structure. The support structure supports the battery plate grid strip above the belt and a gap is provided between a bottom surface of the battery plate grid strip and a top surface of the belt. Battery paste material is dispensed into the gap, through the battery plate grid strip, and overpastes the bottom surface of the battery plate grid strip. ## Claims ### Claim 1 A battery plate grid strip pasting assembly, the assembly comprising: a hopper having adjacent its bottom an orifice with a leading edge and a trailing edge and through which battery paste material is dispensed out of the hopper during use of the battery plate grid strip pasting assembly, a paste delivery roller having an axis of rotation and overlying and in proximity to the orifice for delivering battery paste material out of the hopper;
