<p>Valve mechanism supplying creme on the tops of a succession of two rows of cookies for sandwiching. The cookies are moved along a sandwiching machine by a conveyor beneath a rotating stencil supplying creme to the cookies, under the control of a one-piece valve assuring a uniform supply of creme on the tops of cookies of each row of cookies to thereafter be sandwiched by other cookies supplied to the cremed cookies as passing along the conveyor. The valve is in the form of a one-piece valve block supported at one end and rotationally adjusted to balance the flow through orifices in a stencil sleeve within which the valve is mounted. The creme enters the stencil sleeve from one end of the tube. The stencil sleeve has an outlet port for each row of cookies, which in turn supplies the creme to annular orifices in a rotating stencil, rotating at the speed of travel of the conveyor and the cookies carried thereby. The valve may be adjusted to shut off the flow entirely and proportion the flow between the two orifices to assure the same amount of creme be supplied to the row farthest from the inlet to the valve as to the closer row as the scroll is rotated to supply creme to the two rows of cookies.</p> |
