Needle

FIELD: light industry, in particular, manufacture and usage of sewing needles which may be used in clothing manufacture, everyday and household services, medicine, printing industry and other fields where stitch formation is performed using needle.

SUBSTANCE: needle has thread eyelet formed as cavity provided with helical recess which is opened upon rotation of eyelet. Said recess has widened portions.

EFFECT: reduced labor intensity in operation and wider operational capabilities and range of needles.

The invention relates to light industry, namely for the construction and use of a sewing needle, and can be used in garment factories, domestic service, life, medicine, printing and other fields when performing the seams.

Known needle with an eye for the thread. This eyelet is made in the form of holes /concise encyclopedia of domestic economy / Ed. Nr.: IGOR Terekhov, etc. - 3rd ed. - M.: Large Grew. encyclopedia, 1993. - S, 390/.

This technical solution is characterized by the following disadvantages: increased complexity of operation, due to the difficulty of threading the thread in the eye, made in the form of holes; technological limitations, determined by the necessity of passing the thread through the hole and neoteleostei thread from the eye when performing weld "two trains".

From patent GB 1466395, CL D05B 85/02, 09.05.1977 known needle with an eye for the thread, provided with a spiral slot, which made the drop-down under the action of elastic forces of the compressed thread and is broadening.

This embodiment of the loops increases the complexity of operation of the needle, limits its technological capabilities, reduces operational reliability due to the increased risk of jamming and/or thread breakage.

The objective of the invention is to reduce the complexity of operation, the expansion of technological capabilities and AC is orcement products.

This problem is solved due to the fact that the needle with an eye for the thread, provided with a spiral slot with broadening according to the invention, the eyelet is made in the form of the cavity and the slot is made by drop-down rotation of the eye.

The invention is illustrated by the drawing, which shows a needle, view from the side of the broadening of the slot.

The needle includes a needle in a cavity 1 with slot 2 Bay 3, through which passes the thread 4.

The loops can be placed in the back or at the tip of the needle. The needle may be provided with grooves, blades, rough, relief stations and other devices to facilitate the disclosure of the slot. The cavity may be empty or filled with a substance, for example, for lubrication and/or disinfection threads.

The needle is made by known methods from known materials. When using the needle is rotated ears, and through the open slot of the needle onto the thread or removed from the thread. To facilitate rotation of the eyelet may use the cap key and/or other devices.

The execution of loops in the form of a cavity, provided with a spiral slot with the broadening reduces the complexity of operation of the needle due to the ease of sitting needle for the thread. However due to the possibility of acceding to the needle thread, the ends of which are unavailable or difficult it is available, expand the technological capabilities of using needles. For example, it is convenient to perform a T-shaped, star-shaped and other seams complex configuration by draping needle on intentionally left free thread. Along with this assortment of needles.

Needle with an eye for the thread, provided with a spiral slot with broadening, characterized in that the eyelet is made in the form of the cavity and the slot is made by drop-down rotation of the eye.

FIELD: textile industry, in particular, equipment for manual manufacture of tapestry and like articles.

SUBSTANCE: apparatus has web stretching device made in the form of frame carcass, and embroidering device comprising hollow rectangular handle with opening for extending of tube equipped with sharpened part and longitudinal opening for exit of thread. Outer sides of frame carcass are made conical. Rigidity ribs arranged inside frame carcass are provided with openings for exit of threaded rods fixed on lower ribs of internal shell adapted for recovering of web stretching extent, and on external shell with conical external sides - for clamping web between conical walls. Bolts-handles are designed for releasing web and are adapted for cooperating with thread provided in rigidity ribs on external shell. Embroidering device has mechanism for automatic retaining of pattern profile height. Tube is joined to handle through chuck clamp so that single handle may be used for tubes of different diameters. Handle may be equipped with blind openings for accommodation of tubes. Apparatus of such construction allows web stretching extent to be recovered without necessity of removing web from apparatus and tapestry of any sizes to be manufactured regardless of sizes of stretching device.

EFFECT: provision for forming of relief patterns on any high-density fabrics by means of threads of any thickness and characteristics, with color combinations of one and the same pattern according to user's requirements, and reduced time for making pattern.

FIELD: needle for hand working, preferably designed for weak-sighted people.

SUBSTANCE: hand-held sewing needle has rod provided with arc-shaped curved portion and having one end sharpened and other end provided with eyelet having mutually spring-biased side cheeks and cut terminating in wedge-shaped widened portion at needle end. Eyelet cut is positioned in plane of arc-shaped curved portion of rod. Curved portion of rod is characterized by following parameters: distance from chord to point of arc-shaped curved portion maximally remote from chord is 1-6 mm. Sewing needle of such design enables easy and successful execution of work connected with putting of thread into needle eyelet by weak-sighted people.

EFFECT: simplified construction and wider range of hand-held sewing needles.
