Abstract: A trouser-fly piece serging apparatus includes a guide unit disposed upstream of a serging station and composed of a first elongate guide member extending at an angle relative to the path of movement of a trouser-fly piece being advanced by a serging unit, and a second elongate guide member extending parallel to the path of movement of the trouser-fly piece. The trouser-fly piece is guided by the first guide member into the serging station so that a trimming cutter disposed immediately upstream of the serging unit assumes a position to conform to a curvature of the leading end of a substantially arcuate trimming line passing across a corner of the leading end of the trouser-fly piece. Synchronous operation of the serging unit and the trimming cutter causes the trouser-fly piece to turn in one direction during which an arcuate corner which is trimmed by the trimming cutter and subsequently serged by the serging unit is automatically produced on the leading end of the trouser-fly piece.

Abstract: A button guide turning assembly for automatic button delivery system for delivering buttons from a button supply serially in a given orientation to button affixing apparatus includes a pair of elongate, spaced apart parallel button guides together defining a channel through which the buttons pass in the automatic button feeding system. One of the button guides exerts greater friction on the buttons than the other of the guides, thereby to cause the buttons to rotate. In order to facilitate appropriate spacing of the button guides for buttons of different diameter, a pair of elongate, spaced apart, parallel calibration elements together define at least one button-receiving area. Each calibration element is secured to respective one of the guides for movement as a unit therewith and is configured and dimensioned such that, when the two calibration elements abut a button in the button-receiving area, the guides are appropriately positioned to pass buttons of like diameter through the channel.

Abstract: Method and apparatus is disclosed for the automated forming and hemming of pocket plies or like parts provided with a contoured top flap.

Buttons formed with at least two thread holes are orientated by rotary frictional drive means 60 and 61 through effecting relative rotation between the button support 53 and a button 101 which are located by positioning means 13 and 18 positioning a button above the button support. In the lowest position of the button support, the button support is free to rotate about the vertical axis relative to a button 101 located by the positioning means 13 and 18. In an intermediate position the button support together with the button located by the positioning means 13 and 18 are rotatable about the vertical axis. Pins 54 project upwardly from the button support 53 for insertion in the holes of the button so that the button and button support can rotate together. In an upper position, the button support is locked against further rotation so as to provide a support for buttons in the required orientation.

The apparatus is particularly adaptable for stitching cooperative tapes of "Velcro" to the opposed edges of fabric pieces, such as the margins of an opening in an edge panel in a sofa cushion cover. The overlapping edges with their opposed tapes are compressed into interlocking relationship so that the edges may be retained closed when the fabric pieces are subsequently stitched to other fabric pieces to complete a sofa cushion cover.

Abstract: A button attaching machine has a chute assembly for conveying button parts and a blocking device for preventing button parts from falling from a detachable intermediate chute of the chute assembly when the intermediate chute is detached. The blocking device comprises a spring-loaded plunger supported by the intermediate chute adjacent to a lower end thereof and reciprocably movable in a plane perpendicular to the longitudinal axis of the intermediate chute. The plunger is normally held in engagement with a lower chute to retract away from a button-parts guide channel of the chute assembly, and upon detachment of the intermediate chute, it is movable into a blocking position where it is disposed below the channel and spaced from the lower end of the intermediate chute by a distance which is small enough to block the passage of the button parts.

Abstract: A button attaching machine having an apparatus for preventing button parts from falling from an intermediate chute when the latter is detached from a chute assembly. The apparatus includes a transverse lever pivotally connected at one end to a bracket mounted on a lower end of the intermediate chute, and a blocking member carried on the lever remotely from the bracket and having a first and a second projection. The lever is normally urged by a spring to turn so as to cause the first projection to penetrate into a channel of the chute, thus blocking the passage of the button parts. When the chute is mounted, the second projection is pushed by a stop until the first projection is retracted from the channel of the chute, thus allowing the passage of the button parts.

Abstract: Successive fly strips are continuously sewn to a continuous slide fastener chain by a continuously operating sewing machine as the fly strips are supplied one after another to the sewing machine. During this supplying, a succeeding fly strip is superimposed over a preceding fly strip in a feed station while the preceding fly strip is supplied to the sewing machine and is sewn to the fastener chain. The succeeding fly strip is kept waiting by a stop in its superimposed position for supply to the sewing machine. When the trailing end of the preceding fly strip is advanced by the sewing machine from the leading end of the succeeding fly strip as the sewing of the preceding fly strip progresses, the succeeding fly strip is then supplied to the sewing station at a speed higher than the rate at which the sewing of the preceding fly strip progresses.

Abstract: A button sewing machine has a sewing needle reciprocatingly movable in response to rotation of a main shaft and a button gripping assembly having gripping portions for gripping and releasing a button and movable across the path of reciprocating travel of the sewing needle, the sewing needle and the button gripping assembly being operable together for sewing the button to a fabric. The button sewing machine includes a detector for detecting whether the button is gripped by the gripping portions. After it has been confirmed that the button is gripped by the gripping portions, the main shaft is driven by a control assembly for enabling the sewing needle to sew the button to the fabric.

Abstract: An automatic label emplacer is designed for easy attachment to a commercially-available lock-stitch sewing machine.

Abstract: An automated assembly produces a continuous, contiguous series of individual pieces sewn in a continuously operating sewing machine by conducting successive pieces to the sewing station through a feed station. The feed station may receive the pieces intermittently and irregularly but is equipped with guides and drives for accelerating each successive piece relative to the preceding pieces being sewn in the sewing machine to overtake any spatial gap between the trail end of the preceding piece and the lead end of the succeeding piece so that these ends abut prior to completion of the sewing of the preceding piece. The drives are continuously operating, yet overlapping of the end-to-end relation of the pieces and bunching or furling of the pieces due to this end-to-end abutment are prevented by guide surface confinement of the pieces in the feed station and a predetermined capability for slippage in the drive. The assembly has application in the making of closures for fly openings.

Abstract: A device for guiding a concealed slide fastener to a sewing machine includes a pair of spaced track bodies mounted on a slanted guide plate and each comprising a block fixedly mounted on the guide plate and a cover member movably mounted on said block.
