Publication number: 20040248719Abstract: An object is to provide a preforming apparatus allowing smooth travel of a packaging material (11). The preforming apparatus includes first to fourth guides (34 to 37) for forming a web-like packaging material (11) into a tubular packaging material (11); a longitudinal sealing device (41) for longitudinally sealing the tubular packaging material (11); a drive unit; and a tube guide device (38) disposed in such a manner as to surround the tubular packaging material (11), and guiding the tubular packaging material (11) while being driven by means of the drive unit. Activation of the drive unit causes the tube guide device (38) to guide and feed the packaging material (11), thereby preventing the tube guide device (38) from resisting travel of the packaging material (11). Thus, the tube guide device (38) does not yield a braking effect, thereby allowing smooth travel of the packaging material (11).Type: ApplicationFiled: April 2, 2004Publication date: December 9, 2004Inventors: Keiji Yano, Isao Tezuka, Nobuo Katoh, Kozo Yoshida
