Abstract
Abstract An apparatus for securing a pair of elongated cooperative interlocking tapes to the corresponding edges of a pair of fabric pieces, for guiding the edge portions of the fabric pieces to an overlapping vertically aligned position, and for pulling and compressing the overlapping portions into interlocking engagement. The apparatus is particularly adaptable for stitching cooperative tapes of "Velcro" to the opposed edges of fabric pieces, such as the margins of an opening in an edge panel in a sofa cushion cover. The overlapping edges with their opposed tapes are compressed into interlocking relationship so that the edges may be retained closed when the fabric pieces are subsequently stitched to other fabric pieces to complete a sofa cushion cover.

Claim 1
Independent Claim
416 words
An apparatus for securing a pair of fastener tapes, having cooperative faces, to a pair of fabric pieces, each piece having a longitudinal edge, and to each other, comprising: (a) applicator means for securing a first elongated fastener tape face up to a first fabric piece along the longitudinal edge of said first fabric piece, and for securing a second elongated fastener tape face down to a second fabric piece along the longitudinal edge of said second fabric piece, at an applicator station, said applicator means having front and rear portions, (b) first guide means for guiding said first and second fabric pieces, during movement of said fabric pieces in a longitudinal rearward direction through said applicator station, and in a substantially coplanar position in which the longitudinal edges of said fabric pieces oppose each other. (c) second guide means for guidings said first fastener tape above said first fabric piece and along the longitudinal edge of said first fabric piece, and guiding said second fastener tape below said second fabric piece and along the longitudinal edge of said second fabric piece, during movement of said fastener tapes in said longitudinal rearward direction through said applicator station, (d) rear guide means for guiding said first and second fabric pieces away from said applicator station, said rear guide means being spaced longitudinally rearward of said applicator station and including a lower rear elongated guide member and an upper rear elongated guide member, each of said guide members having front and rear end portions, and each of said guide members comprising an elongated guide element, each guide element being on a longitudinal side of its respective guide member, said guide elements limiting edgewise movement of the fabric pieces guided by said guide members, (e) mounting means mounting said upper rear guide member above and at an angle to said lower rear guide member, said front end portions being spaced transversely of each other relative to said longitudinal direction, and said rear end portions being in substantial vertical alignment with each other, (f) draw means for pulling said first and second fabric pieces into an overlapping relationship from said rear end portions of said lower and upper guide members with said first and second fastener tapes having their opposing cooperative faces in substantially vertical alignment with each other, and for compressing said fastener tapes together to secure said cooperative faces in cooperative engagement, said draw means being behind said rear end portions of said upper and lower guide members.

An apparatus for securing a pair of fastener tapes, having cooperative faces, to a pair of fabric pieces, each piece having a longitudinal edge, and to each other, comprising: (a) applicator means for securing a first elongated fastener tape face up to a first fabric piece along the longitudinal edge of said first fabric piece, and for securing a second elongated fastener tape face down to a second fabric piece along the longitudinal edge of said second fabric piece, at an applicator station, said applicator means having front and rear portions, (b) first guide means for guiding said first and second fabric pieces, during movement of said fabric pieces in a longitudinal rearward direction through said applicator station, and in a substantially coplanar position in which the longitudinal edges of said fabric pieces oppose each other. (c) second guide means for guidings said first fastener tape above said first fabric piece and along the longitudinal edge of said first fabric piece, and guiding said second fastener tape below said second fabric piece and along the longitudinal edge of said second fabric piece, during movement of said fastener tapes in said longitudinal rearward direction through said applicator station, (d) rear guide means for guiding said first and second fabric pieces away from said applicator station, said rear guide means being spaced longitudinally rearward of said applicator station and including a lower rear elongated guide member and an upper rear elongated guide member, each of said guide members having front and rear end portions, and each of said guide members comprising an elongated guide element, each guide element being on a longitudinal side of its respective guide member, said guide elements limiting edgewise movement of the fabric pieces guided by said guide members, (e) mounting means mounting said upper rear guide member above and at an angle to said lower rear guide member, said front end portions being spaced transversely of each other relative to said longitudinal direction, and said rear end portions being in substantial vertical alignment with each other, (f) draw means for pulling said first and second fabric pieces into an overlapping relationship from said rear end portions of said lower and upper guide members with said first and second fastener tapes having their opposing cooperative faces in substantially vertical alignment with each other, and for compressing said fastener tapes together to secure said cooperative faces in cooperative engagement, said draw means being behind said rear end portions of said upper and lower guide members.
Claim 3
Dependent Claim
44 words
The invention according to claim 1 in which each guide element comprises an elongated horizontally disposed channel, each channel including a closed portion facing away from the closed portion of the other channel to engage the edges of the first and second fabric piece.
Claim 4
Dependent Claim
73 words
The invention according to claim 2 in which each of said guide members further comprises a guide flange spaced from the closed portrion of its corresponding channel a distance that is slightly greater than the width of a fastener tape secured to the fabric piece carried through its corresponding channel, and means mounting each of said guide flanges in its corresponding guide member to abut against an inner edge of a fastener tape.
Claim 5
Dependent Claim
30 words
The invention according to claim 3 in which said means mounting said guide flanges comprise spring means biasing each flange toward a fabric piece carried by a corresponding guide member.
Claim 6
Dependent Claim
43 words
The invention according to claim 1 in which said mounting means comprises means pivotally mounting said upper guide member for sustantially horizontal pivotal movement relative to said lower guide member in order to vary the angle between said upper and lower guide members.
Claim 7
Dependent Claim
60 words
The invention according to claim 1 in which said draw means comprises a pair of positively driven upper and lower draw rollers mounted about vertically spaced, parallel, horizontal axes, and means for driving said draw rollers to pull both said first and second pieces through said draw rollers to compress said first and second fastener tapes into said cooperative engagement.
Claim 8
Dependent Claim
