A continuous envelope system for attaching generally conventional paper envelopes to a paper carrier sheet with spots of adhesive adjacent the outer edge of the envelope sealing flap and adjacent the upper edge of the envelope back panel and employing a detacher for subsequently detaching the envelopes from the paper carrier sheet as they are conveyed through the detacher by gradually separating the carrier sheet from the envelopes to form connecting tears therebetween and by severing the connecting tears at the envelopes with the teeth of a severance blade to detach the envelopes without forming unacceptable blemishes thereon.
