Patent ID: 7213808

Claim:
An enclosure-collating device, in particular for mall-processing installations, having: an enclosure-conveying arrangement having driven conveying fingers farming enclosure-conveying compartments on a collating path; and at least one enclosure-feeding device located alongside the collating path and containing a transfer device for introducing individual documents into the enclosure-conveying compartments; wherein the transfer device contains an intermediate conveying device by means of which individual enclosures from a supply of enclosures or a stream of separate enclosures are conveyed in the direction of the enclosure-conveying arrangement to a conveying end position; wherein the conveying end position of the intermediate conveying device is followed by an oblique conveying device which grips enclosures located in the conveying end position of the intermediate conveying device and conveys them with translatory movement, at an angle (90°-α) to the conveying directions of intermediate conveying device into an enclosure-conveying compartment of the enclosure-conveying arrangement; wherein a control unit controls a drive of the oblique conveying device in dependence on the drive speed of the drive or the enclosure-conveying arrangement such that a vector of the speed of an enclosure on account of being driven by the oblique conveying device has a component in the direction of the collating path which is essentially equal to a vector of the drive speed of the conveying fingers; wherein the intermediate conveying device is driven continuously; wherein the intermediate conveying device conveys the enclosures against nips of intermittently driven pairs of rollers of the oblique conveying device, said roller nips, while at a standstill, serving as a stop and wherein the control unit controls the enclosure-collating device such that the enclosure-conveying arrangement is driven intermittently, and the oblique conveying device is switched on intermittently.
