Abstract
An apparatus for transferring adhesive material to portions of filter elements that are displaced relative to the apparatus includes a dispenser from which heated adhesive material is discharged, a transfer arrangement that receives discharged adhesive material and transfers the discharged adhesive material to the portions of the elements as they are displaced, and a cooling arrangement. The cooling arrangement cooperates with the transfer arrangement to cool the discharged adhesive material while the adhesive material is carried by the transfer arrangement to the adhesive material receiving portions of the elements. A process by which adhesive material is transferred to adhesive material receiving portions of the filter elements, as well as an air line panel filter produced by that process, are also discussed.
Claims20
An apparatus by which adhesive material is transferred to adhesive material receiving portions of individual elements that are displaced relative to the apparatus, comprising:
- a dispenser from which heated adhesive material is discharged through a dispenser nozzle,
- a transfer arrangement having an outwardly facing cylindrical surface that receives a bead of adhesive material from the dispenser nozzle, carries the bead of adhesive material, and transfers the adhesive material to the adhesive material receiving portions of the individual elements that are displaced relative to the apparatus,
- a cooling arrangement cooperating with the transfer arrangement to cool the bead of adhesive material while the adhesive material is carried by the transfer arrangement to the adhesive material receiving portions of the individual elements,
- a frame having base elements, a stationary bracket secured near adjacent ends of the base elements, and a subframe pivotally interconnected with the base elements and carrying the dispenser and the transfer arrangement, the base elements securable to side rails of a conveyor for displacing the individual elements relative to the apparatus, and
- an actuation arrangement configured to produce pivotal movement of the subframe relative to the base elements and the stationary bracket to modify the height of the subframe relative to the conveyor and accommodate the individual elements when those individual elements have different thicknesses.
