Abstract: An envelope consisting of a front side and a rear side which are interconnected by side flaps, has a fold-back flap to which a layer of contact adhesive is applied. The adhesive used is a strong contact adhesive which is effective without moistening or activation by any other means. The fold-back flap is laid against the rear side of the envelope for the purposes of transport and storage, an area coated with a parting agent being provided so that the adhesive can be detached before use. The envelope is closed by pressing the otherwise uncoated closing flap onto the adhesive-coated fold-back flap. The adhesive is applied to the fold-back flap by transfer, i.e. the adhesive is applied to the parting agent layer during production and then transferred to the fold-back flap when the latter is redressed.
Abstract: In the process of packaging letter envelopes and mailing wallets, the packaging batch is counted in the end region of the production machine, and the individual article of the packaging batch corresponding to the specific batch size is at least identified or optionally pushed a certain distance sideways out of the path of movement of the packaging batch in one direction or the other as a counting article. The packaging batch is deposited on a conveyor belt and conveyed away. A stack support keeps the stack approximately vertical on its end face. The stack support is advanced in front of the stack at the conveying speed of the conveyor belt. As soon as the counting article at the end of a stack has arrived at a transfer point which is at a relatively long distance from the production machine, a separating device is introduced into the stack, with the result that the following portion of the packaging batch is temporarily halted.
