A overlock sewing machine includes a switch limiting arm rockable integrally with a main shaft fixing operating arm and an arm including arms which are actuated by operating a threading switching knob to engage with the switch limiting arm to rock a rocking lever portion and being engageable with a slide plate to move the position of the slide plate to a sewing executable position upon operating the threading switching knob to the sewing executing position side.

A yarn feed assembly for directing yarn from a wound yarn source to a yarn feed tube having a frame member positioned adjacent to the wound yarn source and defining at least one elongate interior chamber. The yarn feed assembly has a weighted member slideably received in the elongate interior chamber such that, upon pulling one yarn off of the wound yarn source, through a bore of the weighted member and into the yarn feed tube, the weighted member is axially movable along a longitudinal axis of the frame member such that the bore of the weighted member is axially movable about and between a bottom end and a top end of the elongate slot in response to tension applied to the yarn as a result of yarn hang ups on the wound yarn source.

The invention relates to a presser finger (4) which is a component of a winder for winding a roving on to a rotating bobbin (1) with a longitudinal axis (10). The presser finger (4) has a carrying arm (40) with a longitudinal axis (8) and a roving 4 guide element. The presser finger (4) also has a guide plate (5) for guiding the roving on to a rotating bobbin (1). The presser finger (4) is alternatingly movable in the direction (X) of the longitudinal axis (10) of the rotating bobbin (1), and this movement of the presser finger (4) is provided by a drive means. The invention also relates to a roving winder with the aforementioned presser finger (4) and a method of winding a roving with the aid of the aforementioned presser finger (4).

A cable spooling apparatus for use with a storage drum for spooling and storing cable. The cable spooling apparatus comprises a tensioning unit for adjusting the tension of a cable as it is being spooled onto the storage drum. The tensioning unit traverses a path between the opposite ends of the storage drum. Methods of spooling and unspooling cable using the apparatus are also disclosed.

A guide member for use in connection with a wheel of a vehicle includes a wall and a base. The wall extends from a lower surface to an upper surface. The lower surface defines a support plane. The wall has an inner surface and an outer surface. The base extends from the lower surface of the wall. The base has a top surface and a bottom surface. The base is disposed transverse to the wall at a non-perpendicular angle to define a space between the bottom surface of the base and the support plane. The inner surface of the wall and the top surface of the base define a receiving pocket configured to receive a wheel of the vehicle therein, whereby the outer surface of the wall guides a longitudinal flexible member around the wheel of the vehicle.

The present invention relates to a traversing element (1) for a spinning machine (26), wherein the traversing element (1) comprises a guide segment (2) by means of which a roving (3) may be guided in the region of a surface of a tube (4) or of a roving bobbin (5), and wherein the traversing element (1) comprises a support segment (6) via which it may be connected to a support member (7) of the spinning machine (26). According to the invention it is suggested that the traversing element (1) comprises at least one cavity (8) that is closed with respect to the outside and is partially filled with a liquid (9), wherein heat that occurs in the region of the guide segment (2) due to friction between the guide segment (2) and the roving (3) guided by the guide segment (2) when the traversing element (1) is operating may be absorbed by the liquid (9). In addition, a spinning machine (26) having a corresponding traversing element (2) is proposed.

A threading device of a sewing machine includes a flow path switching member, a base portion, and a plurality of thread introducing portions. The flow path switching member includes a gaseous body inlet portion for receiving a compressed gaseous body, a gaseous body outlet portion provided to communicate with the gaseous body inlet portion for exhausting the gaseous body, and a cylindrical outer surface portion at which the gaseous body outlet portion is opened. The base portion includes a cylindrical inner surface portion into which the cylindrical outer surface portion of the flow path switching member is inserted and for supporting the flow path switching member in a rotatable manner, and a plurality of flow paths formed to communicate with the cylindrical inner surface portion. The plurality of thread introducing portions are provided at the base portion to communicate with respective outlet sides of the plurality of flow paths.
