ABSTRACT:
In a collating machine having paper bins with papers therein to be collated, paper ejection arms simultaneously moving the uppermost sheet in each bin with an ejection stroke, and a system collecting the upper-most moved sheets; a feed head on each ejection arm having a mounting bracket, rollers mounted on a shaft journalled in the bracket to roll on papers in a bin, and rachet means preventing rotation of the rollers during the ejection stroke of each arm. The shaft of each feed head is journalled in elongated slots so that withdrawal of an uppermost sheet moves the shaft in the slots to cause electrical contacts to indicate a sheet from each bin has been collated. The rachet means may be a rachet wheel mounted on each shaft and a pawl mounted on each bracket and the electrical contacts may be the rachet wheel and pawl which break contact as each uppermost sheet of a bin is withdrawn by the collection system.
