ABSTRACT:
In a web-type multiple-part business form stock having a succession of serially connected potential outgoing envelopes each containing one or more intermediate layers which may be withdrawn from the outgoing envelopes after the outgoing envelopes are received and opened by an addressee, the hitherto conventionally-used cross-web lines of cold glue used for defining the two opposite edges of the internal spaces of the potential outgoing envelopes is replaced by cross-web band patterns of hot melt adhesive applied in a customary location, but left attached only to the web surface to which it was applied, and which is not heat activated and used to adhere the respective webs together until after the form stock has been variably printed by the form manufacturer's customer, e.g. by an impact printer used in association with a carbon-type or carbonless between-layers coating provided internally of the form stock.
