摘要： Fiberglass filament waste is cut into segments with an apparatus comprised of a feeder that includes a cutting roller having a rotatable shaft with a plurality of spaced circular cutting blades mounted thereon, and a waste feeder having a discharge opening adjacent said roller for conveying said waste into engagement with the periphery of the blades, the feeder including at first and second spaced surfaces extending from a waste inlet opening to a waste discharge opening, at least one of the surfaces being pivotal adjacent the waste inlet opening to expand the discharge opening under pressure from waste being conveyed between the surfaces. At least one of the surfaces, which may be a surface of a conveyor belt, is moveable toward the discharge opening, while the other surface may be stationary, or move toward the discharge opening. In one embodiment, the lower surface moves toward the discharge opening, while the upper surface moves away from the discharge opening to equalize the volume of waste being fed. A slotted stationary plate supports the waste during cutting.

摘要： Fiberglass filament hulls are cut to form fiberglass staple fibers with an apparatus comprising a cutting roller with a plurality of equally spaced, circular, diamond coated cutting blades separated by circular spacers having a diameter less than the diameter of the cutting blades; a circumferentially grooved pressure roller positioned parallel to the cutting roller and forming a nip therewith, with the periphery of the blades extending in non-engaging relation into the grooves; and a conveyor for flattening and conveying the hulls into the nip of the cutting and pressure rollers with the hull filaments being oriented substantially transverse to the blades while the cutting roller is rotated at a significantly greater speed than the pressure roller, whereby the hull filaments are held against the cutting roller by the pressure roller, and cut into staple fiber lengths by the blades.
摘要翻译： 玻璃纤维长丝壳被切割以形成玻璃纤维短纤维，其装置包括切割辊，该切割辊具有多个等间隔的圆形金刚石涂层切割刀片，所述刀片由直径小于切割刀片直径的圆形间隔件隔开; 平行于切割辊定位的周向开槽的加压辊并且与其形成辊隙，其中叶片的周边以非啮合关系延伸到槽中; 以及用于使船体平滑并输送到切割和压力辊的辊隙中的输送机，其中船体长丝基本上横向于叶片定向，同时切割辊以比加压辊更大的速度旋转，由此船体长丝 通过压力辊保持抵靠切割辊，并通过刀片切割成短纤维长度。
