Abstract

A packaging machine for fabricating individual bag-like containers from a continuous web of polyethylene or like material comprising a frame having a substantially elongated configuration on which is mounted a plurality of work stations at least partially defining a flow path along which the web travels as it is being fabricated. A web carrier means in the form of one or more carrier belts supportingly engages said web by finger means to penetrate a predetermined portion of the web by virtue of the finger means being oriented to extend outwardly relative to the interior of the web. A drive assembly is interconnected in driving relation to the carrier means and serves to feed the web along said flow path and to a fill assembly whereby the web material passes into and out of said fill assembly in a predetermined manner to allow for an open orientation or configuration at the fill station to permit filling. Sealing means, carrier guide means and web attachment means are all mounted on the frame in spaced relation to one another at predetermined positions along the flow path to accomplish fabrication of the individual containers.
