Wrapped textile sleeve with bonded closure mechanism and method of construction thereof
A wrapped textile sleeve for protecting an elongate member and method of construction thereof is provided. The sleeve includes an inner layer having opposite inner edges extending lengthwise between opposite inner ends. The opposite inner edges are laterally spaced from one another by an inner width. The sleeve further includes an outer layer having opposite outer edges extending lengthwise between opposite outer ends. The opposite outer edges are laterally spaced from one another by an outer width. An adhesive intermediate layer is sandwiched between the inner layer and the outer layer, wherein a melted portion of the adhesive intermediate bonds the inner layer to the outer layer. The adhesive intermediate layer extends beyond at least one of the inner edges to provide an exposed region of the adhesive intermediate layer. The exposed region is bonded to the outer layer and maintains the outer layer in a wrapped, tubular configuration.
1. A method of constructing a wrapped textile sleeve, comprising:
providing an inner layer having opposite inner edges extending lengthwise between opposite inner ends;
providing a nonwoven outer layer having opposite outer edges extending lengthwise between opposite outer ends;
sandwiching an adhesive intermediate layer between the inner layer and the nonwoven outer layer to form a sandwiched portion of the adhesive layer and an exposed portion of the adhesive layer that extends beyond at least one of the opposite inner edges of the inner layer;
bonding the inner layer to the nonwoven outer layer by heating the sandwiched portion of the adhesive intermediate layer;
wrapping the nonwoven outer layer about a mandrel to bring the portions of the nonwoven outer layer adjacent the opposite outer edges into abutting relation with one another; and
bonding the abutting portions of the wrapped nonwoven outer layer with one another by heating the exposed portion of the adhesive layer.
2. The method of claim 1 further including providing the inner layer as an impervious sheet of polymeric material.
3. The method of claim 1 further including providing the inner layer as a nonwoven material.
4. A method of constructing a wrapped textile sleeve, comprising:
providing an inner layer having opposite inner edges extending lengthwise between opposite inner ends;
providing an outer layer having opposite outer edges extending lengthwise between opposite outer ends;
sandwiching an adhesive intermediate layer between the inner layer and the outer layer to form a sandwiched portion of the adhesive layer and an exposed portion of the adhesive layer that extends beyond at least one of the opposite inner edges of the inner layer;
bonding the inner layer to the outer layer by heating the sandwiched portion of the adhesive intermediate layer;
wrapping the outer layer about a mandrel to bring the portions of the outer layer adjacent the opposite outer edges into abutting relation with one another;
bonding the abutting portions of the wrapped outer layer with one another by heating the exposed portion of the adhesive layer; and
further including aligning one of said inner edges in flush relation with one of the outer edges.
5. The method of claim 4 further including bonding a radially inwardly facing inner surface of the outer layer to the exposed region of the intermediate layer and bonding the exposed region of the intermediate layer to a radially outwardly facing outer surface of the outer layer.
6. The method of claim 1 further including extending the adhesive intermediate layer beyond both of the inner edges of the inner layer to provide a pair of the exposed regions.
7. The method of claim 6 further including bonding the pair of exposed regions to one another.
8. A method of constructing a wrapped textile sleeve, comprising:
providing an inner layer having opposite inner edges extending lengthwise between opposite inner ends;
providing an outer layer having opposite outer edges extending lengthwise between opposite outer ends;
sandwiching an adhesive intermediate layer between the inner layer and the outer layer to form a sandwiched portion of the adhesive layer and an exposed portion of the adhesive layer that extends beyond at least one of the opposite inner edges of the inner layer;
bonding the inner layer to the outer layer by heating the sandwiched portion of the adhesive intermediate layer;
wrapping the outer layer about a mandrel to bring the portions of the outer layer adjacent the opposite outer edges into abutting relation with one another;
bonding the abutting portions of the wrapped outer layer with one another by heating the exposed portion of the adhesive layer; and
further including providing the inner layer with EMI shielding properties.
