Publication number: 20150047300Abstract: Transforming machines for changing a strip of unopened bag precursors into open bag precursors are disclosed that include a drive motor, a separation station, a sensor electrically connected to a controller that is electrically connected to components of the separation station. The separation station includes a first roller, a separation roller driven by the drive motor, and a pressure device having an actuator selectively activating the pressure device to apply pressure to the strip of unopened bag precursors passing over the first roller. In operation, the controller, based on a signal from the sensor, determines when perforations are located in a gap between the pressure device and the separation roller and at that time signals the actuator to activate the pressure device, with the drive motor driving the separation roller, thereby separating the perforations in a first film layer, but not the perforations in a second film layer.Type: ApplicationFiled: October 31, 2014Publication date: February 19, 2015Applicant: INTERTAPE POLYMER CORP.Inventor: Larry C.

Patent number: 7875562Abstract: An improved polyethylene fabric comprises polyethylene fabric or yarn that is manufactured by mixing HDPE (typically in pellet form) with pellets of cyclic-olefin polymers (COCs) in a ratio of up to 40% by weight of the layer. This mixture is then extruded in ways known to those skilled in the art. The resulting HDPE has superior stress and strain characteristics over a wider range of pressures and temperatures than conventional HDPE. The improved polyethylene fabric of the present invention is useful in applications where structural integrity is required and where pressure and temperature are a factor. For example, improved HDPE scrims of the present invention can be used as the reinforcing structure for irrigation hose or building fabric.Type: GrantFiled: May 26, 2006Date of Patent: January 25, 2011Assignee: Intertape Polymer Corp.Inventor: Trevor Arthurs
