Abstract
An adhesive applicator includes an actuation axle, a first hub unit, a second hub unit, a plurality of elastic members, and a pliable dispenser web. The first and second hub units are mounted on the actuation axle to be spaced apart from each other, and to rotate with the actuation axle about a rotation axis. Each of the elastic members is disposed between the first and second hub units, and has a radial elastic force relative to the rotation axis. The pliable dispenser web is configured to wrap around the elastic members, and can be deformed in compliance with a topology of an attachment region of a shoe component against the radial elastic force.
Claims8
An adhesive applicator for applying an adhesive to an attachment region of a shoe component, said adhesive applicator comprising:
- an actuation axle which is mounted to be rotatable about a rotation axis, and which extends along the rotation axis to terminate at a first end segment and a second end segment;
- a first hub unit including
- a first hub body mounted on said first end segment to rotate with said actuation axle about the rotation axis, and
- a first annular flange extending from said first hub body in radial directions to terminate at a first marginal portion;
- a second hub unit including
- a second hub body mounted on said second end segment to rotate with said actuation axle about the rotation axis, and
- a second annular flange extending from said second hub body in radial directions to terminate at a second marginal portion;
- a plurality of elastic springs each of which extends along a lengthwise axis to terminate at a first end region and a second end region, and each of which is stretchable lengthwise so as to have a radial elastic force relative to the lengthwise axis, said elastic springs being angularly displaced from each other in a circumferential direction about the rotation axis, said first and second end regions being configured to be coupled to said first and second marginal portions, respectively, so as to permit said elastic springs to rotate with said first and second hub units about the rotation axis;
- and
- a pliable dispenser web for an adhesive to be spread thereon, which extends in the circumferential direction, and which is configured to wrap around said elastic springs to rotate with said elastic springs about the rotation axis, such that in response to a pressing engagement which is kept between the attachment region of the shoe component and an outer surface of said pliable dispenser web against the radial elastic force during rotation of said pliable dispenser web, said pliable dispenser web is deformed in compliance with a topology of the attachment region, thereby allowing the spread adhesive to be continuously and evenly applied to the attachment region.
