Method and device for placing and attaching a strip inside a tire
The invention presents a device and a method for placing and attaching a strip inside a tire. Specifically, the tire is positioned flat on a mounting between self-centering arms, and an adhesive device is placed inside the tire. While the tire is rotated, the strip is moved inside the tire, wherein a pressure force is applied to said strip. The strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.
1. A method for placing and attaching a strip inside a tire, the strip having a nominal length greater than or equal to an inner circumference of the tire, according to which method:
the tire is positioned flat on a support between self-centering arms having free or motorized ends bearing against a tread of the tire,
an adhesive product is arranged within the tire,
the tire is rotated,
the strip, to which a pressure force is applied, is moved inside the tire,
wherein said strip is driven at a linear speed greater than a rotation speed of the tire, thus producing an effect of compressing said strip, causing the strip, during said process of moving inside the tire, to have a length that becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive product, which adhesive product is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.
2. The method according to claim 1 , wherein the pressure force is applied to the strip as it is moved inside the tire.
