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.

Claims

1. 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.

2. A system for automatic web splicing as claimed in claim 1, wherein the receiving platforms is adapted on the adjusting means for moving and bringing one of the receiving platform in-line with the delivering platform.

3. A system for automatic web splicing as claimed in claim 1, wherein the delivering platform is adapted on the adjusting means for moving and bringing in-line the delivering platform with one of the receiving platform.

4. A system for automatic web splicing as claimed in claim 1 wherein the controller includes a sensor for each web adapted on the running path of web in the unwinding section to sense and activate the controller as the web is finished.

5. A system for automatic web splicing as claimed in claim 1, wherein the dispenser comprises a one-sided adhesive tape, a rubber roller to apply pressure over the adhesive applied web edges, and a vacuum pad to hold front end of the adhesive tape having adhesive side facing towards the web.

6. 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.

7. A system for automatic web splicing as claimed in claim 6, wherein at-least one of the dispensers includes a cutter for cutting the adhesive tape after splicing the webs.

8. A system for automatic web splicing as claimed in claim 7, wherein the cutter is preferably adapted in a top dispenser to cut the adhesive tape after splicing.

9. A system for automatic web splicing as claimed in claim 1, wherein the system comprises a holding means for holding corners of the leading edge of a new web and the trailing edge of a finished web and front edge of the adhesive tape together while splicing the webs.

10. A system for automatic web splicing as claimed in claim 1, wherein the adjusting means moves the platform preferably in a vertical direction.

11. A system for automatic web splicing as claimed in claim 1 further comprises an accumulator to accumulate the spliced web enough to supply web continuously to the utilizing machine during splicing operation.

12. A system for automatic web splicing as claimed in claim 1, wherein the unwinding section comprises a spindle corresponding to each receiving platform for mounting a web core of running web and a web core of new web, a running path for each web.

13. 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.

14. A method for automatic web splicing as claimed in claim 13, wherein the step of applying adhesive tape includes a step of holding the corners of the leading edge of a new web and the trailing edge of a finished web and front edge of the adhesive tape.

15. A method for automatic web splicing as claimed in claim 13, wherein the adhesive tape is preferably applied on top and bottom of the webs simultaneously.

16. A method for automatic web splicing as claimed in claim 13, wherein speed of splicing is dependent on speed of an utilizing machine.
