Abstract:
A spinning plant with a process control computer for at least one group of machines, in which each machine in the group has its own control which controls the actuating elements of the machine (the assembly of auxiliaries allocated to said machine). There is at least one network for bidirectional communication between the computer and each machine of the group. Control commands from the process control computer are taken during the operation of the plant via the network to the machine controls. Each machine control transmits the control commands on to the actuating assembly controlled by said control, the control commands being converted where necessary by the machine control into suitable control signals for the assembly.
Abstract:
A process and device for finding the material flow in a textile processing plant, especially a spinning works, in which the material is processed by a plurality of machines and is transported to and from the machines via conveyor systems and may be stored in at least one point in a store, where the processing machines may consist of several individual processing stations is characterized in that transport processes taking place in at least one conveyor system are detected by sensors without any physical marking of the material units and timed in a computer and related to position data and thereby an initial file is set up containing at least data on the transport processes which have taken place from the material transfert to its discharge point, and in which the material flow from one material transfer point in the conveyor system, e.g. from a discharge point of a processing machine upstream of the conveyor system, to another, e.g. a feed point of a processing machine downstream of the conveyor system, is found by interrogating said file, and/or in at least one processing machine up or downstrem of the conveyor system and having at least one feed and one discharge point, the material flow between said points, without any physical marking of the material units, from a conveyor system to a processing point or vice versa is stored in a or the computer by the time and position recognition and recording of all changes of material units at these points. A second file is thereby produced and the material flow from a feed point to a discharge point at the processing point is found by interrogating the data in said second file, whereby, where necessary, the material flow is found by interlinking the time and place data in the first and second files. Here, the first and/or second files may, if desired, themselves consist of several individual files.
Abstract:
Described is a process for clearing faults in machines, in particular spinning machines, in which fault signals are fed from the machine to a process-control computer which controls the removal of the faults. The process-control computer is used to control an alarm-message transmitter which calls a designated specialist to a particular machine to clear the fault.
Abstract:
Process for operating a ring spinning machine and operating robot (82) for implementing the process. To repair thread breaks, the operating robot (82) has an automatic thread-joining device (136) which, when a thread breaks, first winds one end (102) of an external thread around the spinning head (118). The other end (108) of the external thread is then guided laterally past the upper pressure roller (44) of the drawing mechanism in front of the pair of delivery rollers (42, 44) viewed in the region of the direction of motion of the thread. This other end (108) of the external thread is then moved in the longitudinal direction of the rollers until it is gripped by the gap between the rollers and the fibres of the drawn roving (74) are tied into this end of the external thread.
Abstract:
A textile machine, in particular a ring spinning frame, comprises several drive systems (10, 12) which drive loads at least some of which have different effective forces of inertia. The drive system (10) associated with the load having the greatest effective force of inertia comprises an asynchronous motor (14) whose speed in normal operation is controlled by a supply frequency and which in the event of a power failure operates as a generator excited by a capacitor in order to supply energy to at least one other drive system.
Abstract:
The sail rig is comprised of a quadrangular sail (1) through the sail area of which is arranged from the extremity of the mast (6) down to the foot rope (7) a mast liner (4) wherein an elastic mast (2) of flat cross section aera is inserted. The wishbone (3) or the boom (5) is connected at the front to the luff clew (8) at the rear to the aft leech clew (8). Owing to the convex form, the edge of the sail, i.e. the boltropes, imparts to the sail area delimited by the boltropes an increase tension. Thus, during the tensioning operation, the sail is filled not only horizontally but also vertically. In the case of wind pressure, a concave filling of the sail directed towards the wind occurs. The mast (2) connected to the sail (1) throughout the sail area by the mast liner (4) bends in the same direction as the sail (1). The U-bent luff and aft leech tension produces a triangulation effect of which the action is similar to a tacking, while preventing the masthead from deviating to the leeward side. The tension forces of the sail acting on the mast (2) from the front and from the back are balanced; the forces acting on the mast (2) are therefore low. It is thus possible to build a lighter and more elastic mast (2). The luff without mast offers only a minimum resistance to the air and enhances a laminar flow; as a result, a substantial increase of the advance power and a reduction of the transversal forces are obtained. Furthermore, said sail rig provides a more straight wind attack angle so that it is possible to sail with a higher sail. As the masthead bends when facing the wind due to the wind pressure, the air flow in the higher region of the sail can not be discontinued.
Abstract:
The floating body (1) comprises a stiffening rib (3) embedded, in the longitudinal axis of the floating body, into a body of a porous material (2) of polyethylen or polystyrol foam. The rib (3), which is set on edge and has a uniform width, has a height which gradually decreases from the middle of the floating body towards its ends. The rib (3) consists of a core (4) comprising reinforcement layers (5, 6) of glass fibers on its upper and lower sides. The floating body thus produced has an extremely light weight of about 9 kg and shows very good steering properties, especially as a glider. Owing to the construction and the shaping of the rib (3) it is possible to obtain a stiffness distribution independent of the external shape of the floating body.

Abstract:
Between being finished and their final processing into tailored items, textile webs pass through various processing stages. The faults which may occur during production and processing affect the subsequent steps. The invention proposes to provide a textile web (1) with continuous marking (2) which can be read by a sensor system and thus permits incremental measurement of the web. The influential production data, together with the location, are stored on a web file at each processing station (4). It is thus possible to allocate to each web section (A, B, C) a relevant record (5A, 5B, 5C) which provides for simplified fault detection and possibly elimination and can be transmitted with a precise location to the data of a layout, making it possible to produce faultless products.
Abstract:
In a spinning installation comprising a spinning frame (RSM) with an automatic control unit (BDA) associated with the spinning frame and a subsequent processing machine (SPM) linked to the spinning frame, the automatic control unit has means for collecting data concerning the states of the spinning points of the spinning frame. Means also exist for assigning these collected data to the machining time and transmitting the data so obtained to the subsequent processing machine. The treatment of each individual package delivered by the spinning frame to the subsequent processing machine is adapted by a control system of the subsequent processing machine to the state data generated during the making of the corresponding package. This results in more rational operation of the subsequent processing machine and enhanced quality of the spun product.
