ABSTRACT:
A web material winding machine includes a core tube storage tank, a guiding unit, a transmission means, a web material feeding assembly, a gripping assembly and a second gluing mechanism. A glued core tube is conveyed from the guiding unit to the transmission means and the web material is fed to the transmission means. The transmission means pushes the core tube to move to the gripping assembly and the web material is stuck to the core tube. The web material winds around the working core tube and when the winding is nearly completed, a new core tube is conveyed to the transporting passage and interferes with the feeding speed of the web material, causing the web material to tear along a line of perforations. A tail glue is applied to the web material of the web-wound roll by the second gluing mechanism and a web-wound roll is produced.
