ABSTRACT:
An insert mechanism particularly suitable for opening multiple page, folded, flexible, lightweight "shopper" type paper publications is disclosed which utilizes a pointed pin movable through an arc relative to the path of travel of the paper section which causes the pin to penetrate and lift only a portion of the sheets on the leading corner of the section remote from the fold while the section is advanced along a transport device. The pin is radially secured to a wheel, and the wheel rotates in timed relationship to the advancement of the leading corner of the folded paper. As the pin travels through its arc, it raises the lifted portion of the sheets to a position above a proximal separation shelf. An intermittent air stream directed towards the pin separates and directs downwardly any sheets lifted but not penetrated by the pin. As the section continues to advance on the transport device, the leading corner of the section is disengaged from the pin by a stripper finger, and the corner then falls to the separation shelf. The shelf is of a configuration to further separate the lifted portion from the remaining lower sheets as the section advances, and consequently additional sheets or other materials can readily be inserted within the opened section.
