Abstract
A method of making a floor covering including a tufted textile substrate and a reinforcement backing system. A layer of reinforcement fibers is positioned on the ends of yarn stitches. Applicators are operationally connected such that adhesive is forced into the reinforcement fiber layer towards a primary backing substrate, and adhesive is also substantially simultaneously directed to form a pool of adhesive between the applicators, and a portion of the pool of adhesive is also substantially simultaneously applied as a layer of adhesive on the reinforcement fiber layer.
Claims8
A method of manufacturing a floor covering, the method comprising the steps of:
- manufacturing the floor covering from a group of components including a tufted textile substrate having a primary backing substrate extending in a first direction and a plurality of yarns tufted through the primary backing substrate, the primary backing substrate having a face side and a back side opposite to the face side, a portion of each yarn forming a stitch portion having an end that is located on the back side of the primary backing substrate, and spaces existing between the stitch portions;
- forming a layer of reinforcement fibers on the ends of the stitch portions, and moving said layer of reinforcement fibers in said first direction;
- operably connecting a first applicator to a second applicator and forming a housing for a pool of adhesive, said first and second applicators being movable towards said layer of reinforcement fibers, and providing a passageway in said first applicator for allowing the formation of said pool of adhesive;
- and
- applying controlled pressure with said first applicator to force adhesive into and between the stitch portions on the back side of the primary backing substrate, substantially simultaneously using said passageway for forming said pool of adhesive in said housing, and substantially simultaneously forming, with the second applicator, a cover layer of adhesive on the layer of reinforcement fibers.

A method of manufacturing a floor covering, the method comprising the steps of:
- manufacturing the floor covering from a group of components including a tufted textile substrate having a primary backing substrate, said primary backing substrate being moved in a first direction, and a plurality of yarns tufted through the primary backing substrate, the primary backing substrate having a face side and a back side opposite to the face side, a portion of each yarn forming a stick portion having an end that is located on the back side of the primary backing substrate, and spaces existing between the stitch portions;
- forming a layer of reinforcement fibers on the ends of the stitch portions and moving said layer of reinforcement fibers in said first direction;
- operably connecting a first applicator to a second applicator and forming a housing for a pool of adhesive, said first and second applicators being movable towards said layer of reinforcement fibers, and providing a passageway for allowing adhesive to pass the first applicator and forming said pool of adhesive between said first and second applicators;
- and
- floating said first applicator on said layer of reinforcement fibers, applying controlled pressure with said first applicator to force adhesive into and between the stitch portions, maintaining a gap between said first and second applicators, substantially simultaneously using said passageway for forming a pool of adhesive in said housing, and substantially simultaneously forming, with the second applicator, a cover layer of adhesive over the layer of reinforcement fibers.

- forming a plurality of voids in an adhesive;
- forming a layer of reinforcement fibers on the ends of the stitch portions, arranging the reinforcement fibers to form a patterned layer of reinforcement fibers, and moving said patterned layer of reinforcement fibers in said first direction;
- operatively connecting a first applicator to a second applicator and forming a housing for a pool of said adhesive, said first and second applicators having ends which are spaced from the layer of reinforcement fibers, forming a gap between the ends of said applicators, and said first applicator providing a passageway for allowing said adhesive to move past the first applicator for forming said pool of adhesive between said first and second applicators;
- floating said first applicator on said layer of reinforcement fibers and applying controlled pressure with said first applicator to force adhesive into and between the stitch portions, maintaining said gap between said ends of said first and second applicators, substantially simultaneously using said passageway for allowing adhesive to pass the first applicator and forming said pool of adhesive, and substantially simultaneously forming, with said second applicator, a cover layer of said adhesive over the layer of reinforcement fibers;
- curing the layer of adhesive without eliminating the voids in the adhesive;
- and
- compressing the layer of adhesive and simultaneously collapsing the voids in the adhesive and moving the layer of reinforcement fibers towards the primary backing substrate.
