Abstract
A system for automatic web splicing, comprises of an unwinding section, a splicing section, an accumulator, and a controller to facilitate clamping, cutting and splicing of the webs to provide continuous web supply to a utilizing machine, the system comprises also at least two receiving platforms, a space defining a splicing area between the delivering platform and the receiving platform, one platform for receiving a running web and other platform for a new web and at least one dispenser so as to splice trailing edge of a running web and a leading edge of a new web with an adhesive tape. The system joins the two webs in completely auto mode and keeps the utilizing machine running continuously without stoppage.
Claims16
A system for automatic web splicing adapted on a running path of a web between an unwinding section and a utilizing machine for providing continuous flow of web to the utilizing machine, said system comprising:
- at least two receiving platforms, one platform for receiving a running web and other platform for a new web;
- a delivering platform for delivering running web;
- a space defining a splicing area between the delivering platform and the receiving platform;
- an adjusting means for moving, adjusting, and maintaining the delivering platform and one of the receiving platforms in-line with each other;
- a clamping means for each platform for clamping the webs during splicing;
- a shearing blade for cutting a trailing edge of a finished running web held between the delivering platform and the receiving platform by clamping means;
- at-least one dispenser arranged to travel in cross machine direction within the said space so as to splice trailing edge of a running web and a leading edge of a new web with an adhesive tape;
- and
- a controller to facilitate clamping, cutting and splicing of the webs.
A system for automatic web splicing as claimed any one of the preceding claims, wherein the system preferably comprises two dispensers, arranged above and below running web within the space to apply adhesive tape from top and bottom simultaneously.
A method for automatic web splicing comprising the steps of:
- sensing that running web core is finished;
- clamping the finished web using clamping means;
- cutting the finished web;
- aligning and adjusting leading edge of a new web in-line with a trailing edge of the finished web;
- applying an adhesive tape over the aligned webs and pressing the applied adhesive tape simultaneously;
- and
- cutting the adhesive tape thereby effecting the splicing of the web.
