The fiber bundle drawing apparatus includes: a bobbin holder configured to hold the bobbin in a rotatable state; a turning mechanism configured to receive the fiber bundle drawn from the bobbin, and to turn and deliver the fiber bundle, thereby reducing change in course of the fiber bundle in a direction parallel to a center axis of the bobbin; and a twist prevention mechanism provided between the bobbin holder and the turning mechanism in a path of the fiber bundle in the apparatus, and including a support portion and a rotation suppression portion, the support portion coming into contact with the fiber bundle, the rotation suppression portion being disposed to face the support portion with a gap through which the fiber bundle passes, the gap having a distance greater than or equal to a thickness of the fiber bundle and less than or equal to a width of the fiber bundle.

To provide a wound yarn package and a method for manufacturing the same in which even if sea-island type fibers are wound around a bobbin one by one by a traverse mode, cob-webbing and curling are less likely to occur, and the variation in the heat shrinkage rate between layers constituting the yarn layer is reduced. When winding sea-island type fibers with a fineness of 100 to 6400 dtex around a bobbin one by one by a traverse mode to form a yarn layer, each yarn constituting the n-th yarn layer is wound at a position 0 to x mm away from each yarn constituting the (n1)-th yarn layer, with the yarn width of the sea-island type fiber being taken as x (mm), to fabricate a wound yarn package.

Belt core and belt core systems for winding a belt or other winding material are described. The belt core and belt core system described are lightweight and reusable. The belt core and belt core system includes at least one belt core unit. A plurality of units may be combined to form a belt core system, in which each unit has the same general size and is configured with means for interlocking each unit with another unit. This provides customization of the described system so that it may accommodate a winding material of any width.

A welding device includes a thin film and an ultrasonic welding machine including an ultrasonic welding head welding a first component and a second component of a product together. The thin film is pressed against the product by the ultrasonic welding head and covers a welding area and a non-welding area of the product. The thin film absorbs a vibration energy located in the non-welding area to prevent the vibration energy from being concentrated in the welding area of the product.

Provided is a tape adhering apparatus capable of uniformizing the length of an anisotropic conductive tape to be adhered to a workpiece.

In a tape adhering apparatus (1), a conveying unit (30) intermittently performs an operation of conveying a tape member (T) by a length obtained by adding a gap length (L2) to a predetermined length (L1), and a cutting unit (10) includes a blade holding unit (12) that holds a downstream cutting blade (13) and an upstream cutting blade (14) in a state where the length from the downstream cutting blade (13) to the upstream cutting blade (14) is the predetermined length (L1), and advances toward an anisotropic conductive tape (t1) to cut the anisotropic conductive tape (t1) into the predetermined length (L1) when the conveying unit (30) stops the operation of conveying the tape member (T).

A tape feeder of feeds a component supply tape to a predetermined supply position and peels off a cover tape from the carrier tape at the supply position to expose a component. The tape feeder includes a pair of feed gears configured to mesh with each other and sandwich the cover tape, a drive motor configured to rotationally drive the pair of feed gears such that the carrier tape is pulled in, a rotation gear directly or indirectly meshed with a first feed gear of the feed gears, a one-way clutch provided in the rotation gear such that the rotation gear idles with respect to rotation of the pair of feed gears in a direction in which the carrier tape is pulled in, and a torque limiter provided in the rotation gear or another rotation gear meshing with the rotation gear.
