Abstract

Abstract An apparatus for the guiding and processing of articles such as textile materials of certain lengths which have at least two side edges to be hemmed, including a supply station, a cutting station adapted to cut the material to predetermined lengths as supplied from the supply station, a conveyer for delivering the cut materials away from the cutting station to a sewing station where a hemming operation is performed, the hemmed material is delivered away from the sewing station by a conveyer, a folding apparatus coupled to the delivery conveyer and receiving the material therefrom and performing a folding of material, wherein a pair of sewing stations are arranged parallel with respect to each other and, an intermediate conveyer is arranged after the pair of sewing stations and operating at a higher delivery speed than the conveyer receiving the piece of material from the sewing station, a transfer conveyer arranged along the longitudinal side of the intermediate conveyer for transferring the hemmed piece of material to the folding apparatus.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 210 words
In an apparatus for the guiding and processing of articles such as textile materials of certain lengths which have at least two side edges to be hemmed, comprising a supply station, a cutting station adapted to cut the material as supplied from said supply station to predetermined lengths, first removing means for removing said cut materials away from said cutting station, a sewing station coupled to said first removing means for receiving said material and performing a hemming operation thereon, a second removing means coupled to said sewing station for removing the material away from said sewing station, a folding means coupled to said second removing means and adapted to receive the material therefrom, said folding means performing a folding on said material, wherein the improvement comprises: a. said sewing station comprising a pair of primary sewing means arranged parallel with respect to each other; b. said second removing means comprising an intermediate conveyer means arranged after said sewing means and operating at a higher removal speed than the first removing means, said two sewing means being adapted to feed said conveyer means hemmed material alternately; c. a transfer means arranged along the longitudinal side of said intermediate conveyer means for transferring the hemmed materials therefrom to said folding apparatus.
Claim 2
Dependent Claim 210 words
In an apparatus for the guiding and processing of articles such as textile materials of certain lengths which have at least two side edges to be hemmed, comprising a supply station, a cutting station adapted to cut the material as supplied from said supply station to predetermined lengths, first removing means for removing said cut materials away from said cutting station, a sewing station coupled to said first removing means for receiving said material and performing a hemming operation thereon, a second removing means coupled to said sewing station for removing the material away from said sewing station, a folding means coupled to said second removing means and adapted to receive the material therefrom, said folding means performing a folding on said material, wherein the improvement comprises: a. said sewing station comprising a pair of primary sewing means arranged parallel with respect to each other; b. said second removing means comprising an intermediate conveyer means arranged after said sewing means and operating at a higher removal speed than the first removing means, said two sewing means being adapted to feed said conveyer means hemmed material alternately; c. a transfer means arranged along the longitudinal side of said intermediate conveyer means for transferring the hemmed materials therefrom to said folding apparatus.
Claim 3
Dependent Claim 88 words
The apparatus as claimed in claim 1, wherein said piece of material is removed from said supply station in a predetermined direction, said first removing means removing the cut pieces from said cutting station in a direction perpendicular to the direction of the removal of the material from said supply station, said folding apparatus being arranged in a direction parallel with respect to the direction of removal of said material from said supply station and perpendicular to the direction of removal of said material from said sewing station.
Claim 4
Dependent Claim 50 words
The apparatus as claimed in claim 1, wherein: a. said supply station comprises a pair of supply means, each said supply means having a supply roller means; b. said cutting station comprises a pair of cutting means; and c. each said primary sewing means comprises a pair of sewing means.
