Abstract
A continuous cloth comprising a meltable material comprises one or more cloth units having separation portions therebetween, wherein cloth material of the separation portions has been hot melted, facilitating separation of adjacent cloth units at the respective separation portion therebetween.
Claims28
A cloth comprising:
- a continuous cloth material formed with meltable material, wherein the continuous cloth material defines an upper side, a lower side opposite the upper side, a thickness of the cloth material measured in a direction from the upper side to the lower side, a first marginal edge portion, a second marginal edge portion opposite the first marginal edge portion, and a width of the cloth material extending between the first and second marginal edge portions;
- wherein the continuous cloth material includes a plurality of separation portions each extending from approximately the first marginal edge portion to the second marginal edge portion, each such separation portion is defined by melted and compressed cloth material having a substantially uniform thickness measured in a same direction as the thickness of the cloth material that is less than the thickness of the cloth material and extending substantially uninterrupted from approximately the first marginal edge portion to approximately the second marginal edge portion, the melted and compressed cloth material defines at least one of a decreased toughness or increased brittleness relative to said cloth material and has a tear strength that is less than a tear strength of said cloth material such that the melted and compressed cloth material tears more easily at the separation portion than at said cloth material, and each such separation portion is configured for adjacent cloth units on opposing sides of the separation portion to be separated from each other by tearing along such separation portion to thereby define on each of the separated adjacent cloth units an edge portion to which a portion of the melted and compressed cloth material remains attached to close or seal such edge portion and prevent fraying of said cloth material.
A cloth comprising:
- a continuous cloth material formed with woven fibers of meltable material, wherein the continuous cloth material defines an upper side, a lower side opposite the upper side, a thickness of the cloth material measured in a direction from the upper side to the lower side, a first marginal edge portion, a second marginal edge portion opposite the first marginal edge portion, and a width of the cloth material extending between the first and second marginal edge portions;
- wherein the continuous cloth material includes one or more separation portions at which the cloth material is melted but not broken and extends substantially uninterrupted from the first marginal edge portion of the continuous cloth material to a to the second marginal edge portion, said melted but not broken cloth material having a thickness measured in a same direction as the thickness of the cloth material that is less than the thickness of unmelted cloth material, and each of said one or more separation portions having a tear strength that is less than a tear strength of said unmelted cloth material, such that the cloth tears more easily at the separation portions than at said unmelted cloth material, and wherein each such separation portion is configured for adjacent cloth units on opposing sides of the separation portion to be separated from each other by tearing along such separation portion to thereby define on each of the separated adjacent cloth units an edge portion to which a portion of the melted but not broken cloth material remains attached after said tearing.
