    • A mattress edge sewing machine including a frame having a material supporting surface, a sewing station defined by a needle bar mounted in the frame for generally vertical reciprocatory movements along a fixed centerline, and a feeding mechanism for pulling material through the sewing station of the machine. The feeding mechanism includes upper and lower positively driven feed rollers which are continually biased into operable engagement with each other. The feed rollers are arranged less than 0.8625 inches, measured in the direction of material advancement, separates the centerline of the feed rollers from the centerline of the needle bar. The needle bar is moved in timed relation relative to the movements of the looper, and with the needle bar traversing a distance in a single vertical direction at a ratio greater than 3:1 relative to the distance in a single lateral direction traversed by the looper.
    • 一种床垫边缘缝纫机,包括具有材料支撑表面的框架,由安装在框架中的针杆限定的缝合站,用于沿着固定的中心线大致垂直往复运动;以及馈送机构,用于将材料拉过机器的缝合站 。 进给机构包括上,下主动进给辊,它们被连续地偏置成彼此可操作地接合。 馈送辊布置在材料前进方向上测量的小于0.8625英寸,将进给辊的中心线与针杆的中心线分开。 针杆相对于弯针的移动以定时关系移动,并且针杆以相对于由弯针穿过的单个横向方向上的距离大于3:1的比例在单个垂直方向上移动距离 。

    • A mattress edge sewing machine including a frame with a drive shaft rotatably mounted therein and having a material supporting surface, a sewing station defined by a needle bar mounted in the frame for generally vertical reciprocatory movements along a fixed centerline and a feed mechanism for pulling materials along a generally horizontal direction thereby facilitating advancement of multiple mattress material plies through the sewing station of the machine. The feed mechanism includes upper and lower positively driven feed rollers which are continually biased into operable engagement with each other. The feed rollers are arranged in the line of feed of the material and within a range of about 0.4 inch to about 1.0 inch rearwardly of the needle bar centerline whereby facilitating advancement of material through a sewing station on the machine and especially around four corners of a mattress being sewn. The needle bar is moved in timed relation relative to the movements of the looper, and with the needle bar traversing a distance in a single vertical direction at a ratio greater than 2:1 relative to the distance in a single lateral direction traversed by the looper.
    • 一种床垫边缘缝纫机,包括具有可旋转地安装在其中并具有材料支撑表面的驱动轴的框架,由安装在框架中的针杆限定的缝合站,用于沿着固定中心线大体垂直往复运动,以及用于拉动材料的进给机构 沿着大致水平的方向,从而便于通过机器的缝纫台推进多个床垫材料层。 进给机构包括上,下主动进给辊,它们被连续地偏置成彼此可操作的接合。 进料辊布置在材料的进料线中,并且在针杆中心线后方的约0.4英寸至约1.0英寸的范围内,从而有助于材料通过机器上的缝合站,特别是在四周的 正在缝制床垫 针杆相对于弯针的运动以定时关系移动,并且针杆以相对于由弯针穿过的单个横向方向上的距离大于2:1的比例在单个垂直方向上移动距离 。
