Abstract
Abstract The method and apparatus for fabricating lengths of cloth from a continuous supply of cloth wherein the free end of the supply of cloth is moved onto a cutting platform, prescribed lengths of the continuous supply are cut, and the cut lengths of cloth are then moved in a lateral path with the cut ends disposed generally parallel to the path of travel. One cut end of each of the cut lengths of cloth is hemmed, and the lengths of cloth are then inverted as they are moved through a U-shaped path, and the other end of each length of cloth is hemmed. The hemming function at both ends of the cut lengths of cloth are performed by right handed sewing machines.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
206 words
Apparatus for fabricating lengths of cloth or the like from a continuous supply of cloth comprising a transfer platform, feed means for feeding the end of a generally continuous supply of cloth in a first path onto said transfer platform, sensing means for determining when a predetermined length of cloth has been fed onto said transfer platform, cutting means responsive to said sensing means for cutting a length of cloth on said transfer platform from the supply of cloth, conveyor means for moving the cut length of cloth in a U-shaped path generally normal to the first path, transfer means responsive to said sensing means for urging the cut length of cloth from said transfer platform toward said conveyor means, first edge treating means positioned at one side of said conveyor means in one leg of the U-shaped path for treating one cut edge of the cut length of cloth as the cut length of cloth moves along the U-shaped path, and second edge treating means positioned at the other side of said conveyor means in the other leg of the U-shaped path for treating the other cut edge oF the cut length of cloth as the cut length of cloth moves along the U-shaped path.
Claim 2
Dependent Claim
206 words
Apparatus for fabricating lengths of cloth or the like from a continuous supply of cloth comprising a transfer platform, feed means for feeding the end of a generally continuous supply of cloth in a first path onto said transfer platform, sensing means for determining when a predetermined length of cloth has been fed onto said transfer platform, cutting means responsive to said sensing means for cutting a length of cloth on said transfer platform from the supply of cloth, conveyor means for moving the cut length of cloth in a U-shaped path generally normal to the first path, transfer means responsive to said sensing means for urging the cut length of cloth from said transfer platform toward said conveyor means, first edge treating means positioned at one side of said conveyor means in one leg of the U-shaped path for treating one cut edge of the cut length of cloth as the cut length of cloth moves along the U-shaped path, and second edge treating means positioned at the other side of said conveyor means in the other leg of the U-shaped path for treating the other cut edge oF the cut length of cloth as the cut length of cloth moves along the U-shaped path.
Claim 3
Dependent Claim
62 words
The apparatus of claim 1 and wherein said conveyor means comprises a cylindrical drum rotatable about its longitudinal axis, a first plurality of conveyor belts extending about and engaging said cylindrical drum in an arc of approximately 180* about its curved surface, and a second plurality of conveyor belts urged into engagement with and movable with the first plurality of conveyor belts.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1 and wherein said first and second edge treating means each comprise hemming means constructed and arranged to form a thread chain between the edges of adjacent ones of the cut lengths of cloth, and further comprising cutting means at the sides of the U-shaped path for cutting the thread chains.
Claim 5
Independent Claim
186 words
A method of continuously fabricating cloth lengths or the like comprising moving a continuous length of cloth along its length, cutting lengths of cloth away from the continuous length of cloth at a cutting station, moving at least two conveyor belts into abutment with each other then along a U-shaped path through a first horizontal leg in a direction normal to the length of the continuous length of cloth at the cutting station, around the annular surface of a rotating drum, then through a second horizontal leg, and parting the conveyor belts, moving each cloth length cut from the continuous length of cloth in series into the conveyor belts as the conveyor belts come into abutment with each other and along the U-shaped path with the conveyor belts with the cut ends of the cloth lengths extending along the direction of the path, sequentially treating one end of each cloth length as it moves along the first horizontal leg of the U-shaped path, and sequentially treating the other cut end of each cloth length as it moves along the second horizontal leg of the U-shaped path.
Claim 6
Independent Claim
186 words
A method of continuously fabricating cloth lengths or the like comprising moving a continuous length of cloth along its length, cutting lengths of cloth away from the continuous length of cloth at a cutting station, moving at least two conveyor belts into abutment with each other then along a U-shaped path through a first horizontal leg in a direction normal to the length of the continuous length of cloth at the cutting station, around the annular surface of a rotating drum, then through a second horizontal leg, and parting the conveyor belts, moving each cloth length cut from the continuous length of cloth in series into the conveyor belts as the conveyor belts come into abutment with each other and along the U-shaped path with the conveyor belts with the cut ends of the cloth lengths extending along the direction of the path, sequentially treating one end of each cloth length as it moves along the first horizontal leg of the U-shaped path, and sequentially treating the other cut end of each cloth length as it moves along the second horizontal leg of the U-shaped path.
Claim 7
Dependent Claim
28 words
The method of claim 4 and wherein the steps of treating the cut ends of the cloth lengths comprises trimming and sewing the cloth lengths at their ends.
Claim 8
Independent Claim
145 words
A method of continuously fabricating lengths of cloth or the like from a continuous supply of cloth comprising feeding a continuous length of cloth from a supply along a first path, continually cutting predetermined lengths of the cloth away from the continuous length of cloth as the continuous length of cloth moves along the first path, moving the cut lengths of cloth along a second path approximately normal to the first path without changing the attitude of the cut lengths of cloth, treating one of the cut ends of each length of cloth as the lengths of cloth move along the second path, inverting the lengths of cloth, moving the lengths of cloth along a third path in a direction opposite the second path, and treating the other cut ends of the lengths of cloth as the lengths of cloth move along the third path.
Claim 9
Independent Claim
145 words
A method of continuously fabricating lengths of cloth or the like from a continuous supply of cloth comprising feeding a continuous length of cloth from a supply along a first path, continually cutting predetermined lengths of the cloth away from the continuous length of cloth as the continuous length of cloth moves along the first path, moving the cut lengths of cloth along a second path approximately normal to the first path without changing the attitude of the cut lengths of cloth, treating one of the cut ends of each length of cloth as the lengths of cloth move along the second path, inverting the lengths of cloth, moving the lengths of cloth along a third path in a direction opposite the second path, and treating the other cut ends of the lengths of cloth as the lengths of cloth move along the third path.
Claim 10
Dependent Claim
88 words
The method of claim 6 and wherein the step of feeding the continuous length of cloth from a supply of cloth along a first path comprises feeding the leading end of the continuous length of cloth past a cutting device until a predetermined length of the cloth has moved past the cutting device, and terminating the feeding of the continuous length of cloth until the step of cutting the cloth has occurred and the step of moving the cut length of cloth along the second path has begun.
