Title: Automatic sewing machine - uses time spans for fabric holder movement to give a constant sewing rhythm
IPC: D05B21/00
Filed: 1992-10-12
Abstract: In the control operation for an automatic sewing machine, where the fabric workpiece holder is moved in relation to the needle, an initial time span is set between the start time of the operating start signal and the time when the workpiece holder actually operates and a second time span is set for the workpiece holder movement. The workpiece holder is driven according to the values of the first and second time spans. The steps for each seam are pref. set seam by seam, for each seam in a pattern, and a series of pulses is calculated for each speed for all the seams. Subtraction data are stored matching the stitching pattern data for each seam. A detection system registers at least the movement direction or location of the fabric holder, and modifies the time of either the first or second time span according to the monitored movement direction or location. The setting stage is activated as the fabric holder is driven. The access to stored sewing pattern data is registered, and a time adjustment signal is generated according to at least either the movement direction or movement location in the data, and the position of the needle is detected. The time for the workpiece holder drive is modified within the stored pattern data according to the time adjustment signal and the needle position detection, seam by seam, and for each seam in the pattern. ADVANTAGE - The operation gives a constant sewing rhythm to give improved function and working speed, without damage to the fabric.

Title: Method and device for laminating, in particular, packaging materials
Inventor: SCHNIZER MARTIN
IPC: B31F5/00
Filed: 1993-03-10
Abstract: For the laminating together of sheet- or web-shaped planar materials, for example packaging materials, glue is applied to at least one planar material, whereupon the planar materials are brought together and joined to each other under pressure. In order to be able to laminate the planar materials reliably to each other using a reduced quantity of glue, the relative moisture of the at least one planar material, for example corrugated board, is determined before the application of glue and the quantity of the glue to be applied is set as a function of the moisture value. For this purpose, a corresponding device has a humidity sensor, by means of which the relative humidity of the at least one planar material can be detected, and a computing unit, which receives a moisture signal from the humidity sensor and emits a setting signal to the glue application device as a function of the moisture signal.

Title: Method and arrangement for the interference-free clock recovery for digital signals having a constant bitrate at the receiving end
Inventor: BARTEL WILLY DIPL ING
IPC: H04J3/06
Filed: 1993-05-14
Abstract: The solution according to the invention is used for the interference-free, i.e. as jitter-free as possible recovery of the clock of a transmitting device, operated at a constant bitrate, in the receiving terminal. According to the invention, the incoming cells, having in each case 47 useful bytes, are combined to form periods having the same number of useful byte cells in the cell demultiplexer during the clock recovery. To each period of useful-byte cells, the combination of two combinations of blank-byte groups differing in the total sum of their bytes are combined in dependence on the loading of the splitter memory, which combination, on the one hand, results in a good clock frequency adaptation to the terminal and, on the other hand, in a uniform distribution of the blank-byte groups, the sums of the bytes of which differ, over the entire period. Since it is possible to achieve a very small deviation from the terminal clock frequency by means of the solution according to the invention, it is possible to make the subsequent circuit for clock recovery highly inert with respect to its lower cut-off frequency. <IMAGE>

Title: Transfer-press complex
Inventor: DARR UWE
IPC: B21D43/05
Filed: 1993-06-21
Abstract: In known transfer presses, sliding tables which can be extended transversely to the direction in which the parts travel through the press are provided to facilitate conversion. During conversion, the carrying or feed bars are divided into a plurality of parts by means of automatic coupling systems, and the feed-bar parts assigned to the press areas are moved out in pockets in the respective sliding table.   The novel solution is intended to avoid the complex coupling mechanisms for the automatic separation of the feed bars or decoupling of the gripper slides for the idle stages in the column regions and of the moulding-shell changing devices. For this purpose, the sliding tables (5, 6) of the individual press areas (1, 2) can be coupled mechanically to one another and, upon conversion, can be extended together in or counter to the direction in which the parts run through, and the feed bars (14) are designed to be continuous over the entire length of the press areas (1, 2). For each feed bar (14), separate closing and lifting units are arranged on the press columns (8, 9, 10) to the left and right of the sliding tables (5, 6) - as seen in the direction in which the parts travel through, the closing units together with the feed bars (14) being mounted in such a way that they can be displaced transversely to the direction in which the parts travel through into an outer locked position in order to provide the required free space for the moving out of the sliding tables. <IMAGE>
