摘要： Any type of pattern on each of two layers of fabric is recognized by a camera and the layers of fabric are orientated so that the patterns overlap in the transverse and longitudinal directions. The effects of speed-related fluctuations and pattern-related restrictions are reduced during signal generation. Two-dimensional images of both layers of fabric (7, 8) are produced by matrix cameras (39, 45) during a transport pause. The degree of pattern overlap of the layers of fabric is determined by two-dimensional cross-section analysis of the image points arranged in lines and columns, from which orientation correction values are derived. The distance between the edges of the layers of fabric is measured using a separate section of the matrix sensor determined according to the evaluation. The edge distance data are used to adjust the lower layer of fabric (8) continuously and the upper layer of fabric (7) as necessary, in function of the distance. By accepting slight inaccuracies and by restricting the calculation operations solely to the regions of interest, the total calculating time can be substantially reduced.
摘要翻译：通过照相机识别两层织物中的每一层上的任何类型的图案，并且织物层被定向以使得图案在横向和纵向方向上重叠。在信号发生过程中，速度相关波动和模式相关限制的影响降低。两层织物（7,8）的二维图像在传输暂停期间由矩阵相机（39,45）产生。通过对以行和列排列的图像点的二维横截面分析来确定织物层的图案重叠程度，从中导出取向校正值。使用根据评估确定的矩阵传感器的单独部分来测量织物层的边缘之间的距离。边缘距离数据用于根据需要连续调整织物（8）的下层和织物（7）的上层。通过接受轻微的不准确之处，并将计算操作仅限于感兴趣的区域，可以大大减少总计算时间。

摘要： Any patterns of two layers of fabric are to be recognised by one camera each and the layers of fabric are to be laid out transversely and longitudinally to cover this pattern, where the effect of false values in the signals obtained induced by speed and limitations caused by the pattern are to be reduced. Laminar images of the two layers of fabric (7, 8) are made with one matrix camera (39, 45) each during a conveyor pause. The degree of coverage of the layers of fabric corresponding to the pattern is determined by the two-dimensional cross-relation analysis of the image points arranged in lines and columns. Directional correction values is calculated therefrom. The edge separation of the layers of fabric are detected by a section of the matrix sensors which is separate for assessment purposes. Using the edge separation data the lower layer of material (8) is continuously adjusted and the upper layer (7) adjusted when necessary to the exact distance. Taking account of minor inaccuracies and the limitation of the computing operation to the areas concerned only, the entire computing time may be considerably reduced.

摘要： A device determines the true feed transmitted by a feed device of an industrial sewing machine to the sewn material. The number of threads passing in front of a sensor is counted and the feed is derived from the predetermined thread density. In order to obtain a thread count of maximum precision irrespective of the orientation of the sewn material, a rotating slit diaphragm (7) with at least one parallel-edged radial slit (8) is arranged in front of the photoelectric cell (10) of the sensor. Preferably, a second, stationary slit diaphragm (5) whose angular position can nevertheless be varied comprises a slit (6) which opens over a certain angular range. The rotary slit diaphragm (7) has a larger number of slits (8). The required rotational speed of the rotary slit diaphragm (7) can therefore be reduced. To prevent errors due to the pattern of the fabric, the device can function in the relatively long infrared wavelength range.

摘要： A known sewing machine has a transducer and an electronic evaluation system. The latter checks the threat tension determined by the transducer by comparing it with a threshold value dependent on the preceding stitch. The evaluation of the stitch tension can therefore only take place after the formation of a stitch by a normal variation in the tension after the sewing machine is brought to a halt. When the threshold value is exceeded, a stitch defect is displayed. The invention, on the other hand, proposes a control device for a sewing machine which makes it possbile to display a plurality of different stitch defects as well as problems associated with the needle thread and gripper thread, starting with the first stitch formed by the machine with normal variation of tension. The control device (40) of the sewing machine has a comparator (13; 58) which compares tension peaks (U1, U2,2) of the thread tension (UF) with a predetermined limiting tension (UG1, UG2; UG), and by means of which a switching device (32; 62) arranged downstream and connected to a cut-off device (38) of the drive motor (39) of the machine, as well as a plurality of display elements (33, 35), can be activated, when a tension peak (U1, U2,2) falls below the corresponding limiting tension (UG1, UG2; UG), in function of the limiting tension (UG1, UG2) or of the phase of stitch formation. The switching device (32; 62) thus brings the machine to a halt and switches on the display element (33, 35) corresponding to the defect function.

摘要： Partly overlapping images of typical features of the weave structure (woven or knitted) of each layer of fabric (7, 8) are produced and recorded in a buffer memory as digitalized grey value image signals. The maximum correlation is determined by calculating the cross-correlation function of the overlapping image signals and the feed is determined from this value. The degree of extension of each layer of fabric is determined by calculating the autocorrelation function. If, for example, neither the warp nor the weft threads in a fabric are parallel to the direction of feed, the direction of extension of these threads is determined beforehand. A control signal for a stitch-adjustment device is derived by comparison of the feeds and the degree of extension of the two layers of fabric.
摘要翻译：产生每层织物（7,8）的编织结构（编织或编织）的典型特征的部分重叠图像，并将其记录在缓冲存储器中作为数字灰度图像信号。通过计算重叠图像信号的互相关函数确定最大相关性，并根据该值确定进给。通过计算自相关函数确定每层织物的伸展程度。例如，如果织物中的经纱和纬纱线均不平行于进给方向，那么这些螺纹的延伸方向是预先确定的。通过比较两层织物的进料和伸长程度，可以得到缝合调节装置的控制信号。

摘要： A catch thread device for monitoring quilt stitch and chain stitch grippers. During normal operation of the sewing machine, the thread on the bobbin (3) is used as a reflecting surface. The diffused light rays reflected at the thread enter the light receiver (10) of the catch thread device (8). If the supporting surfaces are not covered by the thread, no light rays enter the photodetector (10), whereupon a warning signal is emitted by a control circuit (12) connected to the photodetector (10).

摘要： The feed device for a belt conveyor ensures, in a technically simple manner, uniform frictional engagement between belt conveyor and workpiece along the feed device. The feed device comprises a retaining strip (10) open at the bottom, one or more pressure hoses (14) with air supply and exhaust, and a strip-shaped pressure-transmitting member (13) in contact with the belt conveyor (6). When the air is evacuated from the pressure hose (14), the contact pressure on the belt conveyor (6), and hence the conveying action of the latter, is discontinued. The feed device is particularly suited for conveying workpieces to sewing aggregates and folding and packaging machines.

摘要： In known top transport devices, a transmission rod for raising the top transport foot is mounted directly on the support element of the support system. This results in a uniform upward movement of the top transport foot. In the new arrangement, the execution of this movement is improved. To reduce the components of motion of the top transport foot in its contact phase, the guide rod drive consists of a pair of guide rods (16, 28) interconnected by a hinge (17) rotatably connected to a rocker (18) mounted on the support element (20) of the support system. The rocker (18) is mounted in such a way that in the contact region of the top transport foot (6) the rocker (18) runs essentially parallel to the guide rod (28) located between the rocker (18) and the top transport foot (6).

摘要： A sewing machine is designed so that the feed dog executes, as desired, either rectangular movements or horizontal sliding movements only. The sewing machine has a lower feed dog to which adjustable horizontal sliding movements are imparted by a drive cam via a stitching actuator and vertical lifting movements are imparted by a drive cam via a pivoting lifting shaft with a lifting cam. A releasable coupling (34-39) is arranged between the lifting shaft (29) and its drive cam (25). The sewing machine can be used both for normal sewing operations, in which the lower feed dog executes a rectangular movement, and for hemming operations in which it may execute horizontal sliding movements only.
