    • A multi-needle quilting machine (10) and method uses two separately moveable bridges (21, 22) having selectively operable chain-stitching element pairs. Either the material (12) or the bridges (21, 22) or both may be moved relative to the frame (11). Control schemes are provided to quilt continuous patterns, discrete patterns, linked multiple patterns, 360 degree patterns, or closely spaced patterns, preferably using a single drive servo motor (35, 36, 45, 46) for each bridge (21, 22) with the needle and looper drives phased relative to each other through a differential transmission. The needles and loopers can be driven out of phase, which is particularly useful in starting stitching sequences reliably. The parameters that define different products are used by a machine controller as a basis for deriving different quilting process steps, such as tack stitch sequences, thread wipe cycles and paths, thread pull-off distances and tension, and the need to sew additional lines to stabilize the material layers. Operator selection between quality and speed modes is provided. Simultaneous sewing of continuous and discontinuous patterns is provided
    • 多针绗缝机(10)和方法使用具有选择性地可操作的链式拼接元件对的两个分开的可移动桥(21,22)。 材料(12)或桥梁(21,22)或两者可以相对于框架(11)移动。 对于每个桥(21,22),优选地使用单个驱动伺服电动机(35,36,45,46)来提供控制方案,所述连续图案,离散图案,连接的多个图案,360度图案或紧密间隔的图案, 针和弯针通过差速传动相对于彼此相位驱动。 针和环可以相位驱动,这在可靠地启动缝合序列时特别有用。 定义不同产品的参数由机器控制器用作导出不同绗缝工艺步骤的基础,例如定位顺序,螺纹擦拭周期和路径,螺纹拔出距离和张力,以及需要缝制附加线 稳定材料层。 提供质量和速度模式之间的操作员选择。 提供连续和不连续图案的同时缝制
