A method for producing a gapless imbricate stream by way of a device, wherein the device contains a gripper conveyor and a conveying-away device, as well as means for transferring two-dimensional product units which are fed by the gripper conveyor to the conveying-away device amid the formation of an imbricate formation, wherein the device forms a transfer region, in which the transfer of the product units from the gripper conveyor to the conveying-away device takes place, wherein at least two product release devices (6a, 6b, 6c) which are arranged one after the other in series in the conveying direction (F G) and distanced to one another, and which are individually activatable for the individual release of the product units, are assigned to the gripper conveyor in the transfer region, containing the following steps of: - feeding a gapless sequence of two-dimensional product units by way of a gripper conveyor, to the transfer region; - releasing the product units at a first product release device; - transferring the released product units to the conveying-away device amid the formation of an imbricate formation, characterised by the following further steps: - detecting a product gap at the gripper conveyor, said product gap connecting to the gapless product sequence, - releasing the last product unit of the gapless product sequence at the first product release device; - lowering the conveying-away speed at the conveying-away device from a regular conveying-away speed to a lower, temporary conveying-away speed; - feeding product units of a subsequent product sequence which are subsequent to the product gap, into the transfer region and further conveying the product units past the first product release device to a further product release device which is arranged downstream in the conveying direction (F G); - increasing the conveying-away speed in a manner such that the regular conveying-away speed is reached again when the first product unit of the subsequent product sequence which is fed by the gripper conveyor catches up with the last product unit of the preceding product sequence which is released to the conveying-away device, - releasing product units of the subsequent product sequence which are directly subsequent to the product gap, at the further product release device arranged downstream and transferring the released product units to the conveying-away device amid formation of an imbricate formation; - releasing the product units of the subsequent product sequence which reach the first product release device, by way of the first product release device, at the earliest on re-reaching the regular conveying-away speed, and transferring the released product units to the conveying-away device amid formation of an imbricate formation, wherein the speed profile of the temporary conveying-away speed is selected such that the first product unit of the subsequent product sequence has caught up in a gapless manner with the last product unit of the preceding product sequence which is dispensed onto the conveying-away device, before or on reaching the further product release device arranged downstream. - feeding a gapless sequence of two-dimensional product units by way of a gripper conveyor, to the transfer region; - releasing the product units at a first product release device; - transferring the released product units to the conveying-away device amid the formation of an imbricate formation, - detecting a product gap at the gripper conveyor, said product gap connecting to the gapless product sequence, - releasing the last product unit of the gapless product sequence at the first product release device; - lowering the conveying-away speed at the conveying-away device from a regular conveying-away speed to a lower, temporary conveying-away speed; - feeding product units of a subsequent product sequence which are subsequent to the product gap, into the transfer region and further conveying the product units past the first product release device to a further product release device which is arranged downstream in the conveying direction (F G); - increasing the conveying-away speed in a manner such that the regular conveying-away speed is reached again when the first product unit of the subsequent product sequence which is fed by the gripper conveyor catches up with the last product unit of the preceding product sequence which is released to the conveying-away device, - releasing product units of the subsequent product sequence which are directly subsequent to the product gap, at the further product release device arranged downstream and transferring the released product units to the conveying-away device amid formation of an imbricate formation; - releasing the product units of the subsequent product sequence which reach the first product release device, by way of the first product release device, at the earliest on re-reaching the regular conveying-away speed, and transferring the released product units to the conveying-away device amid formation of an imbricate formation,
