Abstract of the Disclosure A cutting blade is mounted on an articulated arm for movement into location adjacent a new core and a free running span of the web on a winding machine. An adhesive strip is applied to the new core and then the core is rotated. A pressure roller on an opposite side of the web from the new core then urges the web into engagement with the surface of the new rotating core. As the adhesive strip rotates into contact with the moving web, it causes the web to be deflected into the knife which results in severing of the web. The leading edge of the severed web is maintained adhered to the adhesive strip so that no fold back of the leading edge occurs as the web continues to wind on the new core.
