Abstract: The present invention relates to a semi-automatic device for sewing full felled inseams or outer seams on jeans. The fell seamer employs optical sensors and spline rolls to guide the material into and through the folder. Sensors are embedded in the folder of the device to indicate the amount of material to be introduced into the folder. A computer controlled interface indicates the adjustments to be made and automatically sends instructions to the machine to effect the adjustments. The full fell seamer device includes an upper cylinder assembly, an upper pivot assembly, an upper spline assembly, an upper flex shaft assembly, a lower cylinder assembly, a lower spline assembly, a folder assembly, an upper motor assembly, a lower flex shaft assembly, a control box assembly and a pneumatic assembly. The vision, logic and drive systems sense the material being fed and compute the information gathered and then effect the drive system functioning as required by the material to be sewn.

Abstract: An automatic fabric guide mechanism in a sewing machine includes at least one edge displacement detecting device including a common light source and a pair of light sensors juxtaposed to each other so as to receive rays of light from the common light source. The light source and the light sensors cooperate with each other to define a generally U-shaped channel for accommodating a free lateral edge of a fabric during the feed of the fabric past the stitching position. This detecting device is so designed and so operated as to detect the occurrence of a lateral swing of the fabric being sewed depending on whether both of the light sensors fail to receive the rays of light from the common light source or whether both of the light sensors receive the rays of the light from the common light source.

Abstract: Drive assemblies for seam forming apparatus used to form a seam in one or more limp material segments include a fold assembly and a driver for positioning the segments within guide channels in the fold assembly prior to presentation to a seam joining device. The driver controls the segments to be at associated predetermined positions within the fold assembly. The drive assemblies include actuator means for moving drive wheels of the driver between two positions relative to the guide channels.

Abstract: A seam forming apparatus for forming a full felled seam at one lateral edge of each of two limp material segments establishes a specific geometrical relationship between the segments. The apparatus includes a fold assembly which extends along a reference axis from an input end to an output end. The fold assembly constrains portions of said first and second segments adjacent to the lateral edge to be substantially adjacent and substantially straight in the direction transverse to the reference axis at points near the input end of the fold assembly. Those portions are constrained to be substantially V-shaped in the direction transverse to the reference axis and oppositely-directed and interleaved at points outside and near the output end of the fold assembly. Between the input and output ends, those portions are constrained to be substantially adjacent and substantially Z-shaped in the direction transverse to the reference axis.

Abstract: Fabric parts are fed to a sewing operation through a lap seam folder and the overlapped edges of the parts are maintained in proper relationship by a pair of rollers engageable with the respective parts and mounted for rotation in respective planes of rotation which intersect the feedline of the parts approaching the sewing needle. The rollers are mounted on pivotally supported arms which are operably connected to respective pneumatic cylinder type actuators for moving the arms between operative and retracted positions and for adjusting the biasing force on the arms in accordance with the type of fabric being fed through the seam folder device. The biasing forces on the rollers may be adjusted by adjusting the plane of rotation with respect to the feed direction as well as by the biasing force provided by the respective actuators.

Abstract: An automatic main seam feeding and folding device which has an automatic feeding and folding die which folds two adjacent edges of fabric to form a fell seam and feeds the fabric seam to a sewing machine while maintaining the proper tension and edge alignment. The feeding and folding die folds the adjacent fabric edges from an initial zero degrees of fold to a final overlapping interlocking 180 degree fold to form a main seam and includes tractor dogs along the right and left sides of the die block to continously feed the fabric material. The tractor dogs push the material along the outside of a straight solid die block with the fabric edges to be folded moving within a slot which encloses and contains the fabric spacially. The feeding and folding die is made sufficiently long to enable the two fabric edges to be gradually folded from a parallel planar flat position at the die mouth to a 180 degree, one inch interlocking four layer folded fell seam configuration at the die terminus or nose.

Abstract: A pair of fabric members having proximate abutting margins preliminarily united by a row of basting stitches are then fed through a folder device and folded into a three-ply, Z- or S-shaped construction in preparation for a finished seaming operation. As the members pass through the folder device one of the fabric members is folded along a line on one side of the row of basting stitches to underlie the united margins and the other of the fabric members is reverse folded along a line on the other side of the row of basting stitches to overlie the united margins. The aforesaid folder includes a base plate having an upstanding guide rib or scroll and a generally horizontal guide plate. The guide plate is spaced above the base plate and includes a longitudinal edge forming the line about which the one fabric member is folded to underlie the united margins.

Abstract: A folder for making Z-type folds in material as the material is fed therethrough, having a tongue creating slack in the material and a pair of folder blades cooperating to urge the slack material between the blades to form the fold as the material leaves the folder.

Abstract: A method of making lap seams by providing a constant overlap of the cut edge portions of two pieces of material to be joined together by a seam, stabilizing the overlapping material to prevent relative movement therebetween, rotating the overlapping material causing each piece of material to fold over the cut edge of the other piece of material to form the lap seam, and providing a double row of stitches each extending along a different one of the folded edges of the seam.
