A drum-shaped package formed of a poly(lactic acid)-based monofilament 50 wt. % or more of which is constituted from lactic acid monomer, the drum-shaped package being characterized in that the dry heat shrinking stress of the monofilament in the innermost layer section of the package is 0.04 cN/dtex or less. The drum-shaped package formed of a poly(lactic acid)-based monofilament for which gauze fabric quality and higher order passability during weaving are excellent.

A dispensing cap for a dispensing system may be adapted for dispensing a roll of longitudinally extending material arranged in a center-pull configuration. The dispensing cap may include a dispensing orifice. A first rim having an inner edge may define a wide end of the dispensing orifice. A second rim having an outer edge may define a narrow end of the dispensing orifice. One or more sidewalls may extend between the inner edge of the first rim and the outer edge of the second rim and define the dispensing orifice between the wide end and the narrow end. The dispensing cap may further include a dispensing slot that defines an opening through the second rim.

A polyamide monofilament is characterized in that the abrasion tension thereof when passed through a ceramic guide is 0.3 cN/dtex or less and in that the amount of static electricity generated at the exit of a chromium round bar guide, which is a frictional body, when the polyamide monofilament is passed through the chromium round bar guide, is 300 V or less. This polyamide monofilament and fiber package provide a gauze woven fabric for which tension is low when passing through a thread path guide when warping warp yarn, for which generation of static electricity is suppressed, and which has excellent weaving productivity.

The present invention relates to a stabilizing center core for stabilizing a coil of duct or cable. The stabilizing center core comprises a center tube having a first and a second end. A first plate element is arranged at the first end of the center tube, and a second plate element is arranged at the second end of the center tube. The center core further comprises at least three third plate elements extending between the first plate element and the second plate element and arranged at angular distances around a circumference of the center tube, whereby a duct or cable that is wound around the stabilizing center core is supported by the third plate elements.

A wire reel is detachably provided in a housing chamber of a binding machine body which binds a reinforcing bar. The wire reel includes a cylindrical hub portion which winds a wire, and a pair of parallel flanges overhanging outward from both external peripheral ends of the hub portions. A side wall inside the hub portion is formed of light-transmitting portions which allow the light from a transmissive photosensor provided in the binding machine body to be transmitted therethrough.

The present invention relates to a lower thread bobbin for a sewing machine able to hold a thread, the bobbin comprising a crescent moon-shaped winding part on which a thread can be wound and a crescent moon-shaped securing part for covering the winding part on which the thread has been wound. The lower thread bobbin for a sewing machine has the advantage of being able to hold a greater amount of a lower thread than the very limited amount of a lower thread that is wound on general conventional bobbins, and so increasing the efficiency of sewing work as the user or sewing machinist does not replace the bobbin frequently.
