Abstract: A system and method for controlling the width of a web material supplied to a machine by adjusting the tension of the web material. An operator defines a target web width via an input device. The input device generates a reference signal representative of the target web width. A sensing device senses the width of the web material supplied to the machine and generate feedback signal representative of the sensed width. A control circuit compares the feedback and reference signals and generates a tensioning signal as a function of the comparison. A tensioning device is responsive to tensioning signal for adjusting web tension.

Abstract: A magnetic recording and reproducing apparatus for recording a desired sound or picture signal to a magnetic tape by a magnetic head. At the time of normal-speed recording and reproduction, the magnetic tape is taken up at a constant speed, but by changing the tape travelling speed of the tape on the rotary drum, DTF control and high-speed noiseless reproduction are enabled. The tension of the tape on the entrance side of the rotary drum is controlled to a desired value. This apparatus includes a tape tension actuator and a tape drawing actuator on the entrance side and on the exit side, respectively, of the rotary drum. In DTF control, both tape actuators correct a tracking error of the tape in cooperation with each other. In high-speed noiseless reproduction, both tape actuators are differentially driven so as to lower the tape travelling speed on the rotary drum. Both tape actuators are driven in feedback control using the modern control.

Abstract: A magnetic-tape apparatus is disclosed which includes a drive mechanism for driving a magnetic tape and tape reels, a magnetic-head mechanism buffer mechanism comprising a belt (8), guide elements for guiding the belt in an operational position, a tape-threading mechanism which during the thread-out phase threads the tape out of the cassette and wraps it around the magnetic-head mechanism and during the thread-in phase threads the tape into the cassette. A belt-threading mechanism threads the belt between the guide elements into the tape path during said thread-out phase and brings the belt back into its initial position during the thread-in phase. The apparatus (1) also includes a mechanism for moving the belt-threading mechanism in such a way that the belt can be brought into the desired operational position and into said initial position.

Abstract: A tape transporter is provided with elements to straighten out the normally sinuous tape supply and tape take-up paths of a magnetic tape apparatus in order to facilitate the threading of a magnetic tape into a tape reading and/or recording system. This control of the paths is accomplished by incorporating displaceable guides or idlers into an endless loop the displacement of which is used to control the positioning of the guides or idlers.

Abstract: An integral tape path assembly (110) includes a head subassembly (112), a buffer/guide subassembly (114) and a spaced sensor/guide subassembly (116), all mounted to a common tape path plate (118). The buffer/guide subassembly includes a buffer arm (126) which pivots about an axis shared by a fixed guide (128). A Hall-effect position sensor (186) can be mechanically calibrated via an aperture (142) in a housing (132). The speed sensor/guide subassembly includes a roller (148) which serves to guide the tape on the take-up side of the tape drive system and to drive a shaft (152) holding a speed indicator (156) for a speed sensor (158). The speed sensor/guide subassembly includes a fixed-orientation washer (206) for urging the tape against an upper flange (208) of the roller. The washer is off-center sprung to counter distorting forces engendered by the tape as it engages the roller. Accordingly, a compact tape path assembly is provided requiring a reduced number of precision alignments and minimizing sources of tape distortion.

Abstract: The present invention provides a magnetic tape recorder for recording randomly occurring signals and includes tape supply and takeup reels with associated reel drives and a loop support device to support a loop of magnetic tape extending between the reels. The loop support device is adapted to selectively vary the length of the loop between a maximum and a minimum length. A tape drive capstan and magnetic head are provided between the supply reel and the loop support device to, respectively, transport the magnetic tape from the supply reel to the loop support device and to record data on the tape. Another tape drive capstan and magnetic head are provided between the takeup reel and the loop support device to, respectively, transport the magnetic tape from the loop support device to the takeup reel and to record data on the magnetic tape. An auxiliary capstan is provided to selectively transport the magnetic tape from the takeup reel to the loop support device.The magnetic tape recorder operates through successive cycles in which the magnetic tape is transported in the forward and reverse direction through various modes, namely, a short loop mode, a short loop to long loop mode, a long loop mode, and a long loop to short loop mode. When a signal is recorded on a tape segment the cycle is interrupted, the tape segment is stored on the takeup reel, and the cycle resumed with a supply of unrecorded magnetic tape from the supply reel.
