Abstract: A continuous web of wrapping material for catamenial tampons or other commodities is advanced lengthwise first through a station where it is acted upon by a perforating knife to weaken longitudinally spaced-apart portions of the web transversely of the direction of advancement. The web is thereupon converted into a continuous tubular body and the leader of the tubular body is engaged by a pair of rolls which pull the leader in the direction of lengthwise advancement of the web in order to break the material of the web along successive weakened portions. The thus obtained discrete tubular envelopes are moved sideways, one end portion of each envelope is closed, a commodity is introduced through the other end portion, and the other end portion is closed to confine the commodity at both ends. Such mode of making tubular envelopes ensures that the material of the web is not wasted at all and that the envelopes need not be stored prior to reception of commodities.
