Process for manufacturing fringe headings provided with fringe tassels

Claim 2

A process for manufacturing a tasseled fringe on a warp knitting machine, said tasseled fringe being of the type having a fringe heading tape provided with loops extending beyond an edge of the heading tape, wherein bundles of threads are hooked through said guides to form tassels, and are tied in proximity to the loops, comprising the steps of continuously laying a bundle of threads adapted to form the fringe tassels in a first sinuous path, continuously laying at least one thread adapted to form the loops in a second sinuous path, said thread adapted to form the loops being continuously incorporated into the heading tape, each sinuous path providing a plurality of bends and each alternate bend of each path passing through a different alternate bend of the other path, continuously tying adjacent portions of the bundles of threads adapted to form the tassels adjacent the loops of said second sinuous path, and continuously trimming the bends from said bundles remote from said loops to form said tassels.

Claim 3

A process as claimed in claim 1, further comprising the steps of extending said loops beyond said edge of the fringe heading tape at regular intervals, forming said loops, in part, by weft threads of the heading tape, and interlinking the loops and the tassels at substantially the longitudinal center line of the resulting fringe.

Claim 4

A process as claimed in claim 1 further comprising the steps of feeding the threads adapted to form the loops and the threads adapted to form the tassels by respective thread guides moved over respective paths which extend, in part, transversely of the length of the fringe being formed, said paths and the movements of said threads for forming the tassels to each successive loop extending from said edge of the fringe heading tape.

Claim 5

A process as claimed in claim 3, further comprising the steps of reciprocating the respective thread guide for forming the loops at predetermined intervals over a substantially U-shaped path having two parallel arms and an intermediate bridge portion, the arms of which extend transversely to the direction in which the fringe is being formed, the thread guide for forming the tassels or respectively the thread guide for forming the loops being reciprocated over a rectilinear path extending transversely of the direction in whicH the fringe is formed and intersecting the bridge portion of the said U-shaped path, the reciprocations of said thread guide being over a rectilinear path taking place during parallel but oppositely directed movements of the thread guide travelling over the U-shaped path, and the movements of the said thread guide travelling over the U-shaped path in a direction perpendicular to the said rectilinear path taking place during intermediate pauses in the movement of the said thread guide travelling over a rectilinear path.

Claim 6

A process as claimed in claim 3, further comprising the steps of reciprocating the respective thread guide for forming the tassels at predetermined intervals over a substantially U-shaped path having two parallel arms and an intermediate bridge portion, the arms of which extend transversely to the direction in which the fringe is being formed, the thread guide for forming the tassels or respectively the thread guide for forming the loops being reciprocated over a rectilinear path extending transversely of the direction in which the fringe is formed and intersecting the bridge portion of the said U-shaped path, the reciprocations of said thread guide being over a rectilinear path taking place during parallel but oppositely directed movements of the thread guide travelling over the U-shaped path in a direction perpendicular to the said rectilinear path taking place during intermediate pauses in the movement of the said thread guide travelling over a rectilinear path.

Claim 7

A process as claimed in claim 3, further comprising the steps of moving thread guides for forming the tassels and the loops over respective intersecting substantially U-shaped paths, the open portions of which face away from each other, each reciprocation of the thread guides over their respective paths taking place in three consecutive steps in which the thread guides move in opposite directions along the arms and the bridge portions of the respective U-shaped paths.
