Abstract: A hot-melt adhesive line and an article of manufacture including the same are made up of one or more bundles of fibrous strands (49% by weight) and hot-melt adhesive to effect interfibrous adhesion after heated dispersion throughout the fibers of the strands. The line has an extruded outer layer of compacted adhesive to enclose the strands of the bundle and to adhere by uniform spreading of the entire strand onto a container surface. Typically, 1000 strands of man-made material are included in a hot-melt adhesive line that is 0.024 inch in diameter. Adjoined, side-by-side strands provide tape one-half inch in width.

Abstract: A reinforcement seal and tear tape or line is produced by a method wherein selected fibrous yarn is passed into a bath of hot-melt adhesive maintained at a desired temperature. The yarn is spread laterally and tensioned within the bath to cause the adhesive to penetrate and surround the fibrous yarn. The adhesive adhered to the yarn is extruded within the bath to controllably reduce the amount and cross-sectional shape of the adhesive coating on the yarn by contact with rollers, one of which is submerged in the adhesive bath or a die partly submerged in the adhesive bath. The yarn with an extruded adhesive coating thereon is then cooled by passing through a refrigerated cooling chamber after which the adhesive coating is formed into a desired shape by contact with a chilled-forming surface of superimposed rollers. Reels are then used to coil the coated yarn into spools.
