Abstract: A loom having a deflection beam at the side of the warp for the warp ends and a deflection beam at the side of the cloth for the woven cloth, the deflection beams essentially delimiting the weaving plane containing the shed forming mechanism and the reed. A cover arrangement extends only above the weaving plane essentially from the deflection beam at the side of the warp up to the deflection beam at the side of the woven cloth.

Abstract: The cleaning means employs a nozzle on one side of the picking mechanism which directs a stream of air over the weft yarn in a direction opposite the picking direction to pass through the picking station as well as a funnel on the opposite side of the picking mechanism to receive and exhaust the air with any entrained foreign matter from the picking station.

Abstract: Removable bearer members in the form of rails are removably mounted on studs at the picking and catching side. The bearer members allow the air duct to be moved horizontally out of the vertical plane of the shafts of the shedding mechanism so as to permit removal of the shafts during a warp beam change.

Abstract: When weaving, movable and stationary discs grasp or grip intermittently the weft yarn therebetween. One of the discs has at its contacting surface a circular recess encircled by a bank. The ridge of the bank contacting the flat surface of the other disc does the gripping.

Abstract: An air passage is formed in the weft yarn grasping means to permit the passage of air therethrough upon weft yarn releasing action of the grasping means, so that any yarn waste and miscellanea gathering in the grasping means are removed by the passing air.

Abstract: In a weaving loom including a selvage yarn feeding device usually including a pair of yarn feeding units mounted on and driven by a planetary gear mechanism and each having a yarn guide area in which a selvage yarn being passed therethrough is scraped against various edge portions and thus tend to produce fibrous flues, an apparatus for removing such flues from the yarn guide area of each yarn feeding unit, comprising air-flow inducing means such as flue blow-off means or flue collecting means or a combination of both and valve means which is actuated in cycles synchronized with weaving cycles of the loom so that compressed air is discharged from the flue blow-off means into the yarn guide area and/or suction is developed in the yarn guide area by the flue collecting means whereby the flues deposited in the yarn guide area are splashed therefrom and, if the flue collecting means.

Abstract: An apparatus for use with paper, tissue and like fibrous sheet material rewinding machinery, comprising a booth disposable substantially around the rewinding machinery and having side walls, an intake-end end wall a take-off end opening through which wound rewind bars may be withdrawn, a fixed cover over at least the take-off end, leaving an uncovered top portion at the intake end through which wound reels may be introduced and withdrawn, vent openings in the booth, a moveable cover portion moveable between an inoperative position clear of the intake opening and an operative position in which it forms a closure over the intake opening, means to move the moveable cover between the inoperative and operative positions, and means to induce flow of air from the atmosphere through the vent openings to minimize egress of dust from the booth without substantially disturbing the sheets as they are rewound.

Abstract: A casing is disposed about yarn grasping means, in which yarn waste is collectable, to allow the yarn waste in the casing to be enforcedly exhausted therefrom by the suctorial operation mode by a weft yarn shooting nozzle.
