Abstract
A strip is fastened to an edge of a textile piece by first advancing strip of the ribbon in a direction parallel to the strip of ribbon from a supply. Then a leading end of the strip is gripped a first nip point while advancing additional ribbon from the ribbon supply. The strip is then gripped at a second nip point upstream of the first nip point at a trailing end of the strip. The ribbon is then severed upstream in the strip-travel direction of the second nip point to separate the strip from the ribbon into a sufficient length between the first nip point and the second nip points. The leading or trailing end is then pivoted about at least one pivot axis relative to the other end and positioned near or on the other end, which is then fastened to the edge of the textile piece.
Claims21
A method comprising the steps of sequentially:
- advancing a strip of the ribbon in a strip-travel direction extending parallel to the strip of ribbon from a ribbon supply;
- gripping a leading end of the strip in the strip-travel direction at a first nip point while advancing additional ribbon from the ribbon supply;
- gripping the strip at a second nip point spaced from the first nip point at a trailing end of the strip spaced upstream from the first nip point;
- severing the ribbon upstream in the strip-travel direction of the second nip point to separate the strip from the ribbon into a single strip of sufficient length between the first nip point and the second nip points;
- pivoting the leading end or the trailing end about at least one pivot axis relative to the other end, or
- positioning the leading end or the trailing end relative to the other end, or positioning both ends relative to each other in the plane of the strip or parallel to this plane so that a simple loop or a U-shaped loop or a V-shaped loop is formed in which the leading and trailing ends are oriented one above the other or overlap at least partially or are next to each other;
- aligning the positioned leading and trailing ends are transverse to an edge of a textile piece and positioning the leading and trailing ends thereon, or
- aligning the leading and trailing ends from an aligning position that deviates from a transverse to the edge of the textile piece into a position in which they are positioned transverse to the edge of the textile piece;
- and
- fixing the loop at the ends to the textile piece.
The method defined in claim, wherein the ribbon is advanced intermittently.
A method comprising the steps of sequentially:
- advancing a strip of ribbon in a strip-travel direction extending parallel to the strip from a ribbon supply;
- gripping a leading end of the strip at a first nip point while advancing additional ribbon from the ribbon supply;
- gripping the strip at a second nip point upstream in the strip-travel direction from the first nip point at a spacing of sufficient length between the first nip point and the second nip point to form a loop;
- severing the ribbon upstream in the strip-travel direction of the second nip point to separate from the loop with the leading end and a trailing end gripped at the first and second nip points;
- pivoting the leading end of the strip section about at least one pivot axis relative to the other end;
- positioning the pivoted end relative to the other end;
- aligning the leading end positioned in this way transverse to the edge of the textile piece and positioning it thereon;
- and
- fixing the loop at the leading end to the textile piece.
An apparatus comprising:
- a conveyor for advancing a strip of ribbon in a strip-travel direction extending parallel to the strip from a ribbon supply;
- a first gripper for gripping a leading end of the strip in the strip-travel direction at a first nip point;
- a second gripper for gripping a trailing end of the strip at a second nip point spaced upstream in the direction from the first nip point to form between the nip points a loop of the strip of ribbon;
- a cutter for severing the strip from the ribbon upstream of the trailing end of the strip and of the second nip point;
- a pivoting device that can pivot the first gripper or the second gripper about at least one pivot axis relative to the other gripper, or
- an adjuster that can move the first nip point or the second nip point relative to the other nip point in a plane of the strip or parallel to this plane so that the strip of ribbon forms a simple loop or a U-shaped loop or a V-shaped loop whose ends are one above the other or overlap at least partially or are next to each other and are positionable on and fixable to the edge of the textile;
- a positioning device for positioning the leading and trailing ends at the edge of the textile piece;
- and
- a conveyor that transports the textile piece with the positioned ends of the strip to a fastening device that attaches the leading and trailing ends of the strip to the textile piece.
