Abstract

Oblong articles such as sanitary pads moving in the direction of their length dimension are deposited on article carriers at the lower level of an ascending run of an input closed loop chain conveyor with corresponding one sides of the articles facing up. There are means for pivoting the carriers laterally at the upper level of the run to initiate turning of the articles about the line along which they are being conveyed. They turn 90.degree. by the time they land on the paddles or carriers of an adjacent output conveyor which has a run descending from said upper level to a lower level so the articles which have been turned are also inverted when they complete their descent.
