Abstract:
For use with container production equipment, an apparatus is provided for controllably feeding a consistent stream of carton blanks in shingled form from a stack by applying constant pressure downwardly on a rotating belt which frictionally engages the top carton blanks to remove them from the stack. The preferred arrangement for removing carton blanks includes a device for applying pressure comprising an air pressure cylinder, and includes an arrangement for controlling the pressure applied to automatically maintain a constant pressure. The level of pressure applied may be adjusted to accommodate changing coefficients of friction between the feed belt and carbon blanks, and between adjacent carbon blanks, as well as to control the pressure applied to shingle a series of single carton blanks or to shingle a series of groups of two or more carbon blanks. A positioning arrangement permits positioning the point of application of pressure, thereby allowing adjustment of the shingle length, as well as adjustment to shingle carton blanks of different sizes.
