Abstract
Abstract A web severing apparatus is adapted for use with flexible web material of a kind (a) which is to be withdrawn from a web holder and (b) which has a trailing end portion anchored to the web holder and a free leading end portion. The apparatus includes a web pulling mechanism for pulling such web material, in either of first and second different orientations, longitudinally along a web path from the web holder. When substantially all but the trailing end portion of such web material is withdrawn from the web holder, the web pulling mechanism serves to shift a particular web portion which closely precedes the trailing web end portion laterally out of the web path. A web cutter blade in the apparatus is disposed to sever the free leading web end portion from a remainder of such web material at the web holder, in the event the web material is initially pulled in the second orientation along the web path. Also, the web cutter blade is disposed to sever such web material at the particular web portion which closely precedes the trailing web end portion, when substantially all of the web material has been withdrawn in the first orientation from the web holder and the particular web portion is shifted out of the web path.
