摘要： The invention discloses an apparatus and a method for transporting cut piece in the direction of their longitudinal axis followed by gradually changing the direction of their transport transversely to the longitudinal axis. The invention disclosed has one 10 longitudinal transport device (2), one cross transport device (3) on which apparatus of invention (8) is mounted, and a transverse transport device (4) to transfer cut piece (5) from longitudinal direction to traverse direction. During the direction change, a gripping means (6), which comprises of gripping unit (6', 6''), follows a groove path (19) such that during one cycle of cut piece (5) transfer, the upper and 15 lower gripping units (6', 6'') come in contact with each other such that gap between them is near to zero, thereby gripping the cut piece (5) between them and transporting it gradually along the inclined direction leading to the traverse direction.

摘要： : The invention discloses a circular loom and a method for producing regulated weft pattern fabric where the weave density of weft yarn may be varied. It also discloses a fabric that has congestion zones (28) at predetermined locations. The main motor (1) drives the main drive (2) and a haul-off motor (15) drives a fabric haul-off drive (14). The rotational speeds of both motors (1, 15) are controlled via a main electronic control unit (34). Key weaving parameters are fed to a human machine interface (35). An incher unit (7) is provided at multiple locations along periphery of an E-ring stand (20) to facilitate the operation of the loom. The speed of the haul off motor (15) is decreased with respect to the main motor (1) such the at same interval of time more weft yarn /tape (32) will enter into the weaving pattern to form a cramming effect or congestion zone (28).

摘要： The invention relates to an automatic turret type yarn winding device. The invention provides a device and a method to position spindle precisely in turret type automatic winder, during the bobbin changeover. It involves, during the bobbin changeover process, the step of rotating the turret in at least two discrete rotational movements carried out at controlled speeds, whereby the empty bobbin assumes its accurate winding position. In an important inventive aspect of the invention, the turret rotation is controlled by sensing the current in the motors controlling the spindles. The present invention also discloses a system to control motions of the turret and the spindles. It comprises a first control system (10) to control the rotational motion of the turret and a second control system (11) to control the rotational motion of the spindle. It also comprises a master control system (12) which controls both systems (10, 11) and receives signal/information from and sends command to the two control systems (10, 11).

摘要： The invention discloses a method for producing a storage bag with an integrally formed valve, a resulting bag and an apparatus for producing such a bag. The method is characterised by forming the valve (3) of bag (2) by folding corner (13) of the tubular piece (5) at second open end (8) inwardly to the inside followed by cutting off edge strip (22) of tubular piece (5) with the valve (3) formed and closing the second open (8) end by attaching second sealing strip (25) thereto. In another aspect of the invention at least one hole (29) is made into side wall section (9A and/or 9B) of the tubular piece (5) to establish connection between second sealing strip (25) and at least one side wall (19) of the valve (3). The resultant bag has a valve (3) of height (23) smaller than depth (24) of valve (3) and where second sealing strip (25) is attached to second end (8) of tubular piece (5).

摘要： Pusher elements that move forward and backward are used for forming valves in sack making. Their settings deteriorate over time causing wear and tear adversely affecting accuracy of pusher element's operation. The invention discloses a device for controlling the motion of a pusher element (1) in an automated sack making apparatus which is used for making a multi-angular fold at a corner of a tubular fabric (7) having separated individual layers. The device has an electro- magnetic device with discrete-step-motion (5) that controls the movement of said pusher element (1), and which in turn comprises a close-loop controller (6), and a motion driver (5 A). A method of controlling the motion of a pusher element (1) in an automated sack making apparatus is also disclosed where a step of controlling positioning of pusher element (1), and its acceleration during its forward movement, and its deceleration in its reverse movement precisely and accurately using an electro-magnetic device with discrete step motion (5) in relation to the travelling fabric (7) is disclosed.

摘要： The present invention relates to a system and a method for accurately estimating the thickness of extruded plastic films. In particular, the invention relates to automatic allocation of a recipe-dependent calibration factor and a scanning system dependent calibration factor to the measured thickness to arrive at an accurate estimate. It also discloses making changes to the settings of the film forming die to reduce deviation of the actual thickness from the required thickness of the film. It addresses the problem faced by the conventional extrusion systems where the films are often of unacceptably non-uniform thickness. The invention comprises a PLC Controller unit (5) that is capable of receiving data from and sending it, in the form of electric signals, to other components of the system. PLC controller (5) makes computations of estimated actual thickness computation and computation of deviation of it from the required thickness. The PLC controller is also optionally capable of receiving instructions/data from and sending it to film forming die (6) to adjust the die-lip bolt settings.
