Abstract
Abstract An apparatus for removing pulled threads and the like, from a fabric. The apparatus includes an elongated electrical heating element, a guide surface carried below the heating element for engaging the fabric, and a source of power for selectively energizing the heating element. When the pulled thread, which is twisted to provide an elongated member, is brought into engagement with the heating element, such severs the thread closely adjacent the fabric fusing the ends of the cut thread.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
Apparatus for removing pulled threads and the like on fabric including, A. an elongated electrical heating element, B. spaced conducting means supporting said heating element therebetween and supplying electrical energy thereto, C. a guide surface carried below said heating element engaging the fabric when in operable position maintaining said heating element out of contact with but closely adjacent the fabric, and D. a switch for selectively supplying electrical energy to said heating element through said spaced conducting means, whereby pulled threads may be brought into engagement with said heating element and severed thereby while maintaining said heating element out of engagement with the fabric.
Claim 2
Dependent Claim
104 words
Apparatus for removing pulled threads and the like on fabric including, A. an elongated electrical heating element, B. spaced conducting means supporting said heating element therebetween and supplying electrical energy thereto, C. a guide surface carried below said heating element engaging the fabric when in operable position maintaining said heating element out of contact with but closely adjacent the fabric, and D. a switch for selectively supplying electrical energy to said heating element through said spaced conducting means, whereby pulled threads may be brought into engagement with said heating element and severed thereby while maintaining said heating element out of engagement with the fabric.
Claim 3
Dependent Claim
71 words
The apparatus set forth in claim 1, wherein said spaced conducting means are closed by said heating element to form a loop, whereby a pulled loop of synthetic thread may be inserted and confined in the loop with the guide surface engaging the fabric, to bring the heating element into engagement with the loop of synthetic thread to sever same and join the severed ends when the apparatus is pulled rearwardly.
Claim 4
Dependent Claim
18 words
The apparatus set forth in claim 1, wherein said spaced conducting means carry said guide surface integrally therewith.
Claim 5
Dependent Claim
21 words
The apparatus set forth in claim 1, wherein said guide surface is carried by a support spaced below said conducting mEans.
Claim 6
Dependent Claim
25 words
The apparatus set forth in claim 1, wherein means for controlling the supplying of electrical energy includes a resistance in series with the heating element.
Claim 7
Dependent Claim
21 words
The apparatus set forth in claim 1, including an elongated housing, and batteries carried therein as a source of electrical energy.
Claim 8
Dependent Claim
24 words
The apparatus set forth in claim 1, including an elongated housing, and an AC-DC power pack carried therein as a source of electrical energy.
