Apparatus for bonding ribbon in a nonlinear pattern to a web
View Patent ↗A ribbon applicator configured to guide ribbon to a web includes a support structure and a cantilever arm supported by the support structure. The cantilever arm is moveable through a range of motion relative to the support structure. A guide roller guides the ribbon onto the web. The guide roller is pivotally mounted on the cantilever arm for pivotal movement of the guide roller with respect to the cantilever arm.
1. A ribbon applicator configured to guide ribbon to a web, the applicator comprising:
a support structure;
a cantilever arm supported by the support structure and moveable through a range of motion relative to the support structure; and
a guide roller for guiding the ribbon onto the web, the guide roller being pivotally mounted on the cantilever arm for pivotal movement of the guide roller with respect to the cantilever arm, wherein pivotal movement of the guide roller is dependent on movement of the cantilever arm.
2. The ribbon applicator as set forth in claim 1 wherein movement of the cantilever arm in one direction causes the guide roller to pivot in a generally opposite direction.
3. The ribbon applicator as set forth in claim 1 further comprising a pivot shaft, the cantilever arm being mounted to and extending outward from the pivot shaft.
4. The ribbon applicator as set forth in claim 3 wherein the cantilever arm comprises an attachment end affixed to the pivot shaft, a free end, and an intermediate portion extending between the attachment end and the free end, the guide roller being mounted to the cantilever arm adjacent the free end.
5. The ribbon applicator as set forth in claim 3 further comprises a drive shaft operatively connected to the pivot shaft.
6. The ribbon applicator as set forth in claim 5 wherein the support structure comprises a cam box for operatively connecting the drive shaft to the pivot shaft.
7. The ribbon applicator as set forth in claim 1 wherein the guide roller comprises a bracket, a shaft supported by the bracket, and a roller rotatable mounted on the shaft, the bracket being pivotally mounted to the cantilever arm via a pivot pin.
8. The ribbon applicator as set forth in claim 1 wherein the cantilever arm has a length greater than about 10 inches.
9. Apparatus for bonding ribbon in a nonlinear pattern to a web, the apparatus comprising:
a web source for feeding the web to the apparatus;
an adhesive applicator for applying adhesive in a nonlinear pattern to the web; and
the ribbon applicator set forth in claim 1 , the ribbon applicator being configured to deliver and place the ribbon in a nonlinear pattern on the web such that the ribbon overlies and covers the adhesive applied thereto.
10. The apparatus as set forth in claim 9 wherein movement of the cantilever arm in a first direction causes the guide roller to pivot in a direction that is generally counter to the first direction.
11. The apparatus as set forth in claim 10 wherein the guide roller is pivotally mounted to the cantilever arm via a pivot pin.
12. The apparatus as set forth in claim 9 further comprising a pivot shaft, the cantilever arm comprising an attachment end affixed to the pivot shaft, a free end, and an intermediate portion extending between the attachment end and the free end, the guide roller being mounted to the cantilever arm adjacent the free end.
13. The apparatus as set forth in claim 12 wherein the cantilever arm has a length of approximately 10 inches.
