Abstract

An apparatus for manufacturing a heat retaining multi-ply textile includes an adhesive tank; a lower drive roll partially submerged in the tank; an upper drive roll including spaced, longitudinal projections wherein the projections contact the lower drive roll to bring the adhesive onto the projections; two opposite driven rolls; a first supply spool for moving a continuous upper textile sheet wherein the continuous upper textile sheet moves to have its underside contacted the longitudinal projections when passing the upper drive roll before moves to a joining line of the driven rolls; a second supply spool for moving a continuous lower textile sheet to the joining line of the driven rolls wherein the continuous lower and upper textile sheets are pressed toward each other to form compartments; and an oven for heating in order to produce the production. Down migration can be avoided.

Claims16

Dependent claims

An apparatus for manufacturing a heat retaining multi-ply textile comprising:

a tank filled with adhesive;
a lower drive roll partially submerged in the adhesive;
an upper drive roll including a plurality of spaced, longitudinal projections on a cylindrical, outer surface wherein rotating directions of the upper and lower drive rolls are opposite, and wherein the upper and lower drive rolls are opposite with the longitudinal projections contacting an outer surface of the lower drive roll so as to bring the adhesive onto the projections;
a pair of opposite driven rolls disposed downstream of the upper drive roll;
a first supply spool for steadily moving a continuous upper textile sheet forward wherein the continuous upper textile sheet moves to have its underside contacted the longitudinal projections when passing the upper drive roll before moves to a joining line of the driven rolls;
and
a second supply spool for steadily moving a continuous lower textile sheet to the joining line of the driven rolls wherein the continuous lower textile sheet and the continuous upper textile sheet are pressed toward each other by the driven rolls to cause the adhesive to adhere the continuous lower textile sheet and the continuous upper textile sheet together to form a half finished heat retaining multi-ply textile including a plurality of compartments:
wherein each of the compartments is defined by the upper textile sheet, the lower textile sheet, two open sides of the finished heat retaining multi-ply textile, and two adjacent transverse sealing members formed of the cured adhesive.

5 more elements

An apparatus for manufacturing a heat retaining multi-ply textile comprising:

a pair of opposite drive rolls being intermittently rotated in opposite directions;
a first supply spool disposed upstream of the drive rolls for intermittently moving a continuous upper textile sheet toward a joining line of the drive rolls;
a second supply spool disposed upstream of the drive rolls for intermittently moving a continuous lower textile sheet toward the joining line of the drive rolls so that the continuous upper textile sheet and the continuous lower textile sheet can be pressed together to form a half finished heat retaining multi-ply textile;
a sealing device disposed downstream of the drive rolls and being intermittently activated to press onto the passing half finished heat retaining multi-ply textile to form a plurality of equally spaced, transverse welding lines thereon and a plurality of compartments therein;
and
a pair of opposite driven rolls disposed downstream of the sealing device for further pressing the passing half finished heat retaining multi-ply textile to produce a finished heat retaining multi-ply textile after cooling;
wherein each of the compartments is defined by the upper textile sheet, the lower textile sheet, two open sides of the finished heat retaining multi-ply textile, and two adjacent transverse welding lines.
