摘要： An embroidery machine having a plurality of needle bars mounted parallel to each other for the working of different types and colors of threads, with automatic change of the needle bars driven at the time by a drive shaft. A plurality of needle bars are movably mounted adjacent each other in a common needle bar block which is displaceable transversely to the embroidery movement. A driver is fastened on each needle bar. A drive carriage is movably guided on a guide bar arranged parallel to the needle bars. A drive carriage which is driven from the drive shaft by means of a connecting rod and a crank can be coupled by means of a switch pawl with a contact piece which is also movably guided on the guide bar. The driver of each needle bar is provided with a roller which can be selectively inserted into a fork-shaped recess in the contact piece. On each side of the upper dead-center position of the contact piece there is a separate fixed guide cam for the rollers of the needle bars which are located outside the embroidery position.

摘要： A device for the intermittent interruption of the embroidery needle movement on automatically controlled embroidery- or sewing- machines, particularly multiple head automation embroidery machines, with at least one needle bar, the latter being driven by means of a crank rod and a crank from a drive shaft. The crank rod is pivotally connected with a drive carriage. By means of a pawl the drive carriage can be connected with a driver which is fastened on the needle bar. The driver in its turn is able to be secured in an upper deadpoint position by means of a controllable holding pawl with the simultaneous separation or disconnection of the drive carriage.
摘要翻译：一种用于在自动控制的刺绣或缝纫机，特别是多头自动化绣花机上间歇地中断刺绣针运动的装置，其具有至少一个针杆，后者由曲柄杆和曲柄驱动传动轴。曲柄杆与驱动支架枢转连接。通过棘爪，驱动器托架可以与固定在针杆上的驱动器连接。驾驶员又可以通过可控制的夹持爪固定在上死点位置，同时分离或断开驱动托架。

摘要： An apparatus for the drive of the thread take-up on multi-head embroidery machines with at least one embroidery needle in each head, with which the thread take-up comprises a thread take-up lever, which thread take-up lever is mounted on the embroidery head pivotable back and forth about a horizontal axis and is driven by the machine main shaft. The thread take-up levers of all embroidery heads are secured on a common thread take-up shaft, the latter extending over the entire length of the machine. The thread take-up shaft is driven by a crankdrive mechanism from the main shaft of the machine.
