The present invention relates to a conveyor that includes at least one dogging device. The dogging device includes a plurality of dogging yokes (105). These are arranged to move commonly after one another and in mutually spaced relationship in a transport direction. The conveyor is constructed to move booklets (1) piece-wise in the transport direction, by virtue of a pair of adjacent dogging yokes (105) being arranged to straddle a side edge of a booklet (1) with clearance in the transport direction. The object of the invention is to avoid an oblique or inclined orientation of the booklets between the dogging yokes. According to the invention, there is provided a support device (106) which acts between two adjacent dogging yokes (105) which at least partially bridge the clearance when one side edge of a booklet (1) is straddled by the adjacent dogging yokes (105). The invention also relates to a method for moving booklets, wherein one side edge of a booklet (1) is straddled by dogging yokes (105) with clearance in the transport direction. The clearance is reduced subsequent to straddling of a booklet.
A conveyor that comprises at least one dogging device that includes a plurality of dogging yokes which are arranged to jointly move in a transporting direction in mutually spaced and sequential relationship, wherein the conveyor is adapted to move booklets in said transport direction with the aid of a pair of mutually adjacent dogging yokes that are arranged to straddle, with clearance, a side edge of a booklet in the transport direction, including a support device which bridges said clearance at least partially and which acts between two mutually adjacent dogging yokes when one side edges of a booklet is straddled by said mutually adjacent dogging yokes, characterized in that the support device includes springy elements that are adapted to take support against one of said two dogging yokes.
A method for moving booklets in a transporting direction with the aid of a conveyor, comprising the steps of straddling one side edge of a booklet with clearance in said transporting direction by a pair of dogging yokes that are located adjacent one another, jointly moving said dogging yokes in said transporting direction in mutually spaced and sequential relationship, employing a support device to at least partially bridge said clearance, and applying a spring force against the booklet, said spring force being biased by an adjacent dogging yoke, whereby said clearance is caused to be eliminated subsequent to straddling of the booklet.
