摘要:
A fill yarn holding apparatus for use on an air jet loom of the type used for weaving certain fabric patterns where each pattern has at least two fill yarns introduced between each harness reciprocation, and including a pivotal sley shaft, a reed mounted on the sley shaft, at least one air jet for propelling fill yarns across the length of the reed, after which the reed beats the successive fill yarns against the fell line of the fabric being woven, and the harnesses cross to lock in the weave pattern. The fill yarn holding apparatus includes at least one holding air nozzle mounted on the sley shaft of the loom, the holding air nozzle having an opening formed and positioned to direct a jet of air against the previously laid fill yarn transversely to the path of the fill and toward the fell line, and wherein when the air jet propels a fill yarn, the holding air nozzle operates at a selected time to discharge air against the fell line to hold the fill yarn in place until the reed beats up to create a uniform weave pattern.
摘要:
A fabric for use in safety apparel comprising a first set of yarns comprising at least 60 percent modacrylic fibers, and a second set of yarns comprising at least some anti-static carbon filaments. The fabric meets at least the high visibility standard ANSI/ISEA-107-2010; the vertical flame test ASTM 1506-10w; and the Federal Test Method Standard 191A, Method 5931 for electrostatic decay, and the Electrostatic Discharge Association Advisory ADV11.2-1995 voltage potential.
摘要:
A scaffold table for sheet rock finishers includes a horizontal planar base with subtending walls and a spaced apart U-shaped border wall that together define a U-shaped elongate slot sized to cradle wide-bladed masonry tools therein. The table includes a pair of pivotally mounted adjustable length legs having channels on one end to rest against a horizontal scaffold bar. The forward portion of the table includes an elongate hook member to fit over a higher scaffold bar for removably attaching a table thereto. The table base is reinforced from below and includes at least one vertical hole therethrough for cradling of a nail gun or similar power tool.
