A tape feeder for at least two tapes (8,11) which can be taken from a stock is arranged on a sewing machine. The tape feeder has a controlled feed-in device (12) which is arranged transversely to the workpiece feed direction (16), in such a way that it can move, and which has a motor driven shaft (13), which transports tape as desired to the presser foot (6) on the sewing machine. A cutting device (14) arranged on the feed device (12) enables the tapes to be cut off.

A machine for sewing a binding tape to a cut edge of carpeting comprises a wheel-mounted sewing machine having an opposed pair of pinch rollers engaging opposed sides of the carpeting, the pinch rollers being inset from the cut edge and one of the rollers being intermittently motor driven in synchronism with the reciprocating movement of the sewing machine's needle assembly. As the one pinch roller is driven, the sewing machine moves along the floor as the binding tape is played from a reel, folded longitudinally and stitched to the carpet edge. The machine incorporates a spring-biased needle guide which effectively surrounds the needle shank as it moves reciprocally up and down to create the stitches. This guide prevents deflection of the needle and possible breakage thereof should it encounter a hard object, such as a glue bead or the like in the carpet backing. The wheels on which the sewing machine rides are mounted on the bottom on a pan-shaped base which supports the sewing machine and prevents soiling of the carpet by lubricating grease. The pan-shaped base also shields certain of the mechanical linkages of the sewing machine from damage incident to rough handling.

The present invention relates to an apparatus for sewing a label to a piece of fabric. The label is passed through a guiding channel until it is detected by a label sensor activating an air nozzle. The air stream ejected therefrom drives the label into a take-over station. The latter is constituted by two grippers arranged at a defined distance from each other and each consists of a lower and an upper gripper jaw clamping the edges of the label therebetween. Feed cylinders shift the grippers with the label held by them to the sewing site. The distance between the grippers can be varied with the aid of a threaded spindle assembly so that handling of labels of different sizes is possible.

Apparatus for securing an elastic band in a hem tunnel formed of garment fabric comprises a fabric folding device having an entry zone and an exit zone both of which are planar, the entry zone being inclined at an angle, conveniently between 30.degree. and 90.degree., preferably 45.degree., relative to the exit zone. A guide roller by which a band is guided to the entry zone is rotatable about an axis parallel with the entry zone and at right angles to the direction of feed of the band and fabric through the device. The apparatus facilitates the incorporation of draw-cord elastic into garment hem tunnels.

A garment, such as a child's sleeper, having a body portion made of sheet material, without seams, and provided with a longitudinal opening and closure means therefor, such as a slide fastener. The longitudinal opening is for putting the garment on a child and taking it off.The invention also includes a method and means of making such garment.
摘要:
A label dispenser in which data about the label length and the position of the reading marks on the labels is programmed into an electronic control mechanism which advances the labels accordingly by an electronically controlled stepping motor. A stationary light sensor is positioned a fixed distance from a knife blade and provides input to the electronic control. The electronic control may also control a clamp, a folding mechanism and a blowing mechanism.

An accessory unit (2) for a sewing machine (1) for automatically sewing pieces of ribbon material (20) onto a sewing material (5), has a hollow guide shaft (23) with a longitudinal slot (24) to guide the ribbon material (20). A needle (25) is used as an advance feed mechanism and can be inserted through the slot (24) into the ribbon material (20) which passes through the guide shaft (23), by means of which the ribbon material (20) can be advanced in the longitudinal direction of the guide shaft (23). The accessory unit (2) can be swivelled around a vertical axis (x) by at least 90.degree. relative to the sewing machine (1).
摘要:
A method of manufacturing the outer cloth bag for an upright vacuum cleaner in which the bag material of a predetermined width is unwound from a reel an fed through guides, material folders and a double headed sewing machine. At the same time zipper chains are fed from rolls on the right and left side of the moving bag material. The zippers are sewn on opposite side edges of the bag, the bag material is cut into predetermined sized panels, and thereafter the side edges of the panels are folded and the zipper halves zipped up to form a tube. At least one open end is closed to form a bag.
摘要:
A stitching guide for attachment of a zipper to a base material comprising a strip of elongated material having at least one substantially straight longitudinal edge, a plurality of in-line perforations in the strip extending along a longitudinal line substantially parallel to the straight longitudinal edge, and at least one slot in the strip, the slot having a geometrical configuration adapted to circumscribe the slide on the zipper. The perforations in the strip are centrally located for pin insertion during centered zipper application and offset for pin insertion during lapped zipper application. The strip is preferably sufficiently flexible to allow pin insertion and is tinted and may have measurement indicia along the straight longitudinal edge.
