    • An apparatus and method for separating strands of floss, string, thread or yarn from a bundle. One embodiment of an apparatus for separating strands of floss, string, thread or yarn from a bundle that consists of an attachment device (12) with low mass, low moment of inertia and low rotational air resistance that attaches to one end of the bundle (10). The opposing end of the attachment device (12) is connected to a swivel assembly (14). The opposing end of the swivel assembly (14) is attached to a rotational energy absorption device (16) with higher mass, higher moment of inertia and higher rotational air resistance. The rotational energy absorption device (16) is depicted in one embodiment as a bob. Other embodiments are described and shown.

    • A face mask comprising an elongated sheet of porous material having upper and lower longitudinal edges and transverse side edges. A line of stitches of elastic material is sewn to the material along both its side edges, and a length of elastic cord at each side edge is secured to the material by interweaving with the line of stitches thereat. A free intermediate portion of the elastic cord is formed between the ends at which the cord is interwoven with the stitches to the porous material, and the free intermediate portion forms an ear loop. The elastic material is sewn to the porous material and interwoven with the cord lengths while the porous material is taut so that when the porous material is relaxed, the elastic material exerts a pull on the porous material to gather and contract the material at the side edges. In the manufacture of the masks, the porous material is continuously withdrawn from a roll thereof by drive rollers and advanced through a sewing machine where the line of stitches is continuously sewn along each of the opposite side edges of the material while the material is taut. The cord is periodically interwoven along each side edge with the line of stitches, and a cutter downstream of the sewing machine cuts the porous material transversely thereof at successive spaced locations at which the cord is interwoven with the line of stitches.
    • 一种面罩,其包括具有上下纵向边缘和横向侧边缘的多孔材料的细长片材。 一条弹性材料的线迹沿其两个边缘缝合到材料上,并且每个侧边缘处的弹性绳的长度通过与其上的线迹交织而固定到材料上。 弹性绳索的自由中间部分形成在绳索与针脚与多孔材料交织的端部之间,游离中间部分形成耳环。 将弹性材料缝合到多孔材料上并与绳索长度交织,同时多孔材料被拉紧,使得当多孔材料松弛时,弹性材料在多孔材料上施加拉力以在侧边缘处收集和收缩材料 。 在制造掩模时,多孔材料通过驱动辊从辊中连续地取出,并通过缝纫机前进,其中线材沿着材料的每个相对的侧边缘连续缝合,同时材料被拉紧。 缝线沿着每个侧边缘周期性交织,并且缝纫机下游的切割机在连续间隔开的位置处横向地切割多孔材料,在该间隔处,绳索与线迹交织在一起。

    • There is provided a draping conveyor having a narrow upper margin, a flatwork piece feeding means for feeding sequentially flatwork pieces to a draping station, and flatwork piece engaging means for engaging the flatwork piece at the draping station and pushing a portion thereof over the top of the narrow margin of the conveyor as the feeding means continues to operate, so the flatwork piece is draped over the conveyor with a fold located on one side thereof and the confronting portions thereof extending from the fold depending and both exposed on the other side of the conveyor. The draping conveyor is moved first to a sewing station on the opposite sides of which sewing machines are positioned so operators can readily grasp the exposed end portions of the flatwork piece delivered thereto and apply the same to their sewing machines simultaneously. The flatwork pieces fed sequentially to the draping station are formed from the unwound portion of a roll of flatwork piece forming material which is carried by said feeding means past a severance station. The feeding means is momentarily stopped to allow a severing means to move across the flatwork piece forming material to sever a flatwork piece from the end of the unwound portion of the roll of such material.
    • 提供具有窄的上边缘的悬垂式输送机,用于将顺序的平板部件供给到悬垂工位的平坦部件进给装置和用于在平铺台处接合平板部件并将其部分推到其顶部的平板部件接合装置 当输送装置继续操作时,输送机的窄边缘继续运行,因此,平板部件被覆盖在输送机上,折叠位于其一侧,并且其相对的部分从折叠部分延伸并且两者暴露在另一侧 输送带。 悬挂式输送机首先移动到缝纫机定位的相对侧的缝纫站,以便操作者可以容易地抓住递送到其上的扁平件的暴露端部并将其同时施加到缝纫机上。 顺序地供给到悬垂站的平整件由从所述进料装置经过分离台承载的一卷平板成形材料卷的展开部分形成。 进给装置暂时停止,以允许切割装置移动穿过平板部件成形材料,以从这种材料卷的退绕部分的端部切割平整件。
