Abstract
A method for applying measured amounts of viscous material in a predetermined pattern in registry to a continuously moving sheet is provided which includes the steps of introducing the viscous material into a rotary valve having a bore in the valve rotor operatively communicative with the fluid inlet, and a passage radially communicating between the axial bore and an opening in the valve seat through which the material is dispensed onto the sheet stock. The length of the material dispensed to the sheet stock is determined by a slot formed on the surface of the valve rotor which surrounds the opening for the radial passage. Registry of the pattern is accomplished by correlation of the rotation of the valve with the rate by which the sheet material passes underneath the valve orifice. The valve containing the slot and related apparatus is also part of the invention.
