ABSTRACT:
Method of producing chipboards includes conveying elongated cauls end-to-end sequentially past a material-dispensing device, forming a mat of the dispensed material on the cauls, severing the mat transversely to chipboard lengths, feeding the severed mat lengths together with the cauls into a heating press and beating and compressing the same to form chipboards, withdrawing the chipboards and cauls together from the heating press and separating them from one another, and continuously reconveying the cauls past the material-dispensing device.
In apparatus for carrying out the method, an endless conveyor for conveying the cauls end-to-end has entrainer dogs engageable with abutment rods on the cauls for advancing the cauls in a substantially horizontal conveying direction along an upper run of the conveyor located below the material-dispesing device.
