Abstract
Abstract A slide fastener having terminal fastener elements reduced in size relative to the remaining fastener elements and two stop members adjacent the terminal fastener elements, each stop member being formed from a mass of fusible material fused onto a slide fastener tape, the reduced terminal fastener elements accommodating the diamond of a slider when the slider engages the stop members to prevent splay of the slide fastener tapes. A method of forming the above described slide fastener including supporting a slide fastener chain to expose the terminal fastener elements, reducing the size of the terminal fastener elements, and fusing a mass of fusible material onto each slide fastener tape to form the stop members. Apparatus for forming the above described slide fastener including a support block having parallel channels for receiving separate slide fastener tapes, a forming anvil having a pair of spaced legs movable in the channels to capture the terminal fastener elements in cavities therein, a source for supplying ultrasonic energy to the forming anvil to reduce the size of the terminal fastener elements, a forming block supporting the separated slide fastener tapes adjacent cavities defined therein by another forming anvil, a forming member engaging the forming block to move the forming block relative to the other forming anvil and shear blanks of fusible material in the cavities, and a source for supplying ultrasonic energy to the forming member to fuse the blanks onto the slide fastener tapes to form separate stop members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
A slide fastener comprising tape means carrying continuous fastener element means thereon, said tape means having a top portion and said fastener element means having an integral terminal portion adjacent said top portion; top stop means secured to said top portion of said tape means adjacent said terminal portion; and slider means receiving said fastener element means to control interengagement thereof, said slider means being formed to be limited in movement by engagement with said top stop means and having a diamond portion disposed adjacent said terminal portion when said slider means engages said top stop means, said terminal portion being reduced in size transverse to the axis of said fastener and relative to interengaged elements of said fastener element means so as to provide a sufficient space wherein said diamond portion of said slider means is accommodated without causing said tape mean to splay.
Claim 2
Dependent Claim
145 words
A slide fastener comprising tape means carrying continuous fastener element means thereon, said tape means having a top portion and said fastener element means having an integral terminal portion adjacent said top portion; top stop means secured to said top portion of said tape means adjacent said terminal portion; and slider means receiving said fastener element means to control interengagement thereof, said slider means being formed to be limited in movement by engagement with said top stop means and having a diamond portion disposed adjacent said terminal portion when said slider means engages said top stop means, said terminal portion being reduced in size transverse to the axis of said fastener and relative to interengaged elements of said fastener element means so as to provide a sufficient space wherein said diamond portion of said slider means is accommodated without causing said tape mean to splay.
Claim 3
Dependent Claim
20 words
A The invention as recited in claim 1 wherein said fastener element means includes a continuous filament of deformable material.
Claim 4
Dependent Claim
23 words
The invention as recited in claim 2 wherein said top stop means includes a mass of fusible material fused to said tape means.
Claim 5
Dependent Claim
44 words
The invention as recited in claim 1 wherein said terminal portion includes a first terminal element and a second terminal element, said first terminal element being smaller than said second terminal element and disposed between said top stop means and said second terminal element.
Claim 6
Dependent Claim
21 words
The invention as recited in claim 4 wherein said fastener element means is formed from a continuous filament of plastic material.
Claim 7
Dependent Claim
37 words
The invention as recited in claim 5 wherein said continuous filament of plastic material has a coiled configuration with the coils forming said first and second terminal elements being reduced in size relative to the remaining coils.
Claim 8
Dependent Claim
237 words
A slide fastener comprising first and second tapes having first and second top portions, respectively; a first continuous plurality of fastener elements secured to said first tape and including first terminal elements disposed at said first top portion; a second continuous plurality of fastener elements secured to said second tape and including second terminal elements disposed at said second top portion; said first and second fastener elements each being made of a continuous filament of deformable material formed such that said first and second fastener elements are adapted to interengage; first and second stop members attached to said first and second top portions of said first and second tapes adjacent said first and second terminal elements, respectively; and a slider receiving said first and second fastener elements and adapted to control the interengagement theReof, said slider being formed to be limited in movement by engagement with said first and second stop members and having a diamond portion disposed between said first and second terminal elements when said slider engages said first and second stop members, said first and second terminal elements being reduced in size transverse to the axis of said fastener and relative to the remainder of said first and second fastener elements, respectively, so as to provide a sufficient space wherein said diamond portion of said slider is received between said first and second terminal elements without causing said first and second tapes to splay.
Claim 9
Dependent Claim
237 words
A slide fastener comprising first and second tapes having first and second top portions, respectively; a first continuous plurality of fastener elements secured to said first tape and including first terminal elements disposed at said first top portion; a second continuous plurality of fastener elements secured to said second tape and including second terminal elements disposed at said second top portion; said first and second fastener elements each being made of a continuous filament of deformable material formed such that said first and second fastener elements are adapted to interengage; first and second stop members attached to said first and second top portions of said first and second tapes adjacent said first and second terminal elements, respectively; and a slider receiving said first and second fastener elements and adapted to control the interengagement theReof, said slider being formed to be limited in movement by engagement with said first and second stop members and having a diamond portion disposed between said first and second terminal elements when said slider engages said first and second stop members, said first and second terminal elements being reduced in size transverse to the axis of said fastener and relative to the remainder of said first and second fastener elements, respectively, so as to provide a sufficient space wherein said diamond portion of said slider is received between said first and second terminal elements without causing said first and second tapes to splay.
Claim 10
Dependent Claim
