Abstract
An apparatus for sewing finishing a piece cut from a length of textile material unwound from a roll and closing the leading edge thereof, comprising: advancement rollers for advancement of the length of textile material, to unwind two successive portions of the length of material, for a total longitudinal extension equal to the longitudinal extension of the piece; a cutting blade suitable to cut a piece from the length of textile material with a cut that is perpendicular to the unwinding direction and forms the rear edge of the cut piece and the leading edge of the length of textile material to be unwound; and positioning elements for arranging the leading edge of the unwound length of material with respect to a sewing machine.
Claims13
An apparatus for sewing finishing a piece out from a length of textile material unwound from a roll and closing a leading edge of the length of textile material, comprising:
- advancement means for causing advancement of said length of textile material to unwind along an unwinding direction two successive portions of said length of textile material, for a total longitudinal extension equal to the longitudinal extension of the piece to be finished;
- cutting means, arranged downstream of said advancement means to cut said piece from said length of textile material with a cut that is perpendicular to said unwinding direction and forms a rear edge of the cut piece and the leading edge of the length of textile material to be unwound;
- positioning means, arranged downstream of said cutting means;
- and a sewing machine having a sewing path arranged at said positioning means, said positioning means being adapted to oscillate through a 90° angle for arranging and block the leading edge of said unwound length of material at said sewing path of said sewing machine;
- and said advancement means, said cutting means and said positioning means being coordinately operatable so that said advancement means unwind said length of material for a said first portion whose longitudinal dimension is such that said leading edge is engaged in said positioning means, said positioning means oscillate through said 90° angle to position said leading edge in alignment with and at the sewing path of said sewing machine, said sewing machine produces a stitched seam along said leading edge, said advancement means unwind a said second portion from said length of material, and said cutting means cut a piece from said length of material.
An apparatus for sewing finishing a piece cut from a length of textile material unwound from a roil and closing a leading edge of the length of textile material, comprising:
- advancement means for causing advancement of said length of textile material to unwind along an unwinding direction two successive portions of said length of textile material, for a total longitudinal extension equal to the longitudinal extension of the piece to be finished;
- cutting means, arranged downstream of said advancement means to cut said piece from said length of textile material with a cut that is perpendicular to said unwinding direction and forms a rear edge of the cut piece and the leading edge of the length of textile material to be unwound;
- positioning means, arranged downstream of said cutting means;
- and a sewing machine having a sewing path arranged at said positioning means, said positioning means comprising a strip that is oscillatable through a 90° angle between a position arranged flush with said unwinding direction of the length of textile material and a position for blocking the leading edge of said unwound length of material at said sewing path of said sewing machine;
- and said advancement means, said cutting means and said positioning means being coordinately operatable so that said advancement means unwind said length of material for a said first portion whose longitudinal dimension is such that said leading edge is engaged in said positioning means, said positioning means oscillate through said 90° angle to position said leading edge in alignment with and at the sewing path of said sewing machine, said sewing machine produces a stitched seam along said leading edge, said advancement means unwind a said second portion from said length of material, and said cutting means cut a piece from said length of material.
An apparatus for sewing finishing a piece out from a length of textile material unwound from a roll and closing a leading edge of the length of textile material, comprising:
- advancement means for causing advancement of said length of textile material to unwind along an unwinding direction two successive portions of said length of textile material, for a total longitudinal extension equal to the longitudinal extension of the piece to be finished;
- cutting means, arranged downstream of said advancement means to cut said piece from said length of textile material with a cut that is perpendicular to said unwinding direction and forms a rear edge of the cut piece and the leading edge of the length of textile material to be unwound;
- positioning means, arranged downstream of said cutting means;
- and a sewing machine having a sewing path arranged at said positioning means, said positioning means being provided oscillatable through a 90° angle between a vertical position in which the positioning means are arranged flush with said unwinding direction of the length of textile material and a horizontal position for blocking the leading edge of said unwound length of material at said sewing path of said sewing machine;
- and said advancement means, said cutting means and said positioning means being coordinately operatable so that said advancement means unwind said length of material for a said first portion whose longitudinal dimension is such that said leading edge is engaged in said positioning means, said positioning means oscillate through said 90° angle to position and block said leading edge in alignment with and at the sewing path of said sewing machine, said sewing machine produces a stitched seam along said leading edge, said advancement means unwind a said second portion from said length of material, and said cutting means cut a piece from said length of material.
