Abstract: A method for producing bags containing fiber material, comprises the steps of forming at least one continuous layer of fiber material; separating in succession portions of fiber material from the continuous layer and moving them along a predetermined path; feeding each portion of fiber material to respective containment and compaction elements of a first transfer conveyor; feeding an ordered succession of bags containing respective portions of fiber material to respective supporting elements of a second transfer conveyor; transferring the portions of fiber material from the first transfer conveyor inside respective containment bags carried by the second transfer conveyor; transferring the containment bags housing respective portions of fiber material from the respective supporting elements of the second transfer conveyor to a fourth transfer conveyor; and moving in succession the bags housing respective portions of fiber material to a folding unit at which the bags are closed.

Abstract: A method of making secure the use of a piece of software, the method consisting: in a substage of generating modified data (D?): for a first category of users possessing a generation unit (11g) including at least one generation secret (Sg) to be able to obtain modified data (D?); and for a second category of users not possessing the generation unit (11g), to be able at best to generate original data (D) without being able to translate it in order to obtain modified data (D?); and in a substage of reconstituting original data (D): for a first category of users possessing a reconstitution unit including at least a reconstitution secret, to be able to restore the original data (D); and for a second category of users not possessing the reconstitution unit, to be able at best to use the modified data (D?).

Abstract: The invention provides a method of making a user piece of software secure by means of a user processing and memorizing unit (11u) containing at least one user secret (Su). According to the invention, the method consists in: making a user piece of software and modified data (D?) available to a user; and in a stage of running the user piece of software with the associated modified data (D?), enabling the user possessing the user unit (11u) to recover the original data (D) from the modified data (D?).

Abstract: A strap reserving control device for a strapping machine is to apply the relative action between a balancing weight unit and a balancing rod respectively fixed at the opposite ends of a rotating shaft, and the functions of sensing by a sensing portion of a sensing switch to control the amount of packaging strap stored in a strap reserving room. The balancing weight unit and the balancing rod is formed with a lever structure therebetween, therefore no tiredness of elasticity or damage may happen to them, able to prolong the service life of the machine, and stably and precisely control the amount of packaging strap stored in the strap reserving room.

Abstract: A rod-actuating strap control device for a strapping machine includes a rod-interacting unit composed of an actuating rod and a weight rod assembled on a rotary member and the relative action produced between the rod-interacting unit and a press rod as well as the balanced rod with cooperation of the sensing function between a sensing switch and the actuating rod to effectively control the length or amount of the packaging strap stored in a strap reserving room. The operation between the actuating rod of rod-interacting unit and the weight rod is based on a lever structure, therefore no tiredness of resilience or damage of a twisting spring may happen to them, able to prolong the service life of the machine and control the length or amount of packaging strap stored in a strap reserving room with great precision and stability.

Abstract: An apparatus and method for automatically producing door panels in a single line in order to enable continuous production are provided. In the apparatus, a first uncoiler supplies the wound inner plate material. A first leveler regulates a flatness of the inner plate material. A press forms a pattern on the inner plate material. A marking device marks a cutting position on the inner plate material from the presser. A bend controller controls a bend of the inner plate material from the marking device. A second uncoiler supplies an outer plate material. A second leveler regulates a flatness of the outer plate material supplied from the second uncoiler. A roll forming device roll-forms both edges of the inner and outer plate materials. A heater preheats the inner and the outer plate materials. An injector injects insulated material between the inner and outer plate materials. A marking sensor senses the mark on the inner plate material and outputs a sensing signal.

Abstract: A broad swing arm having a finger at its swinging end extends from an axis near a fixing unit to a tractor, overtop and next to a continuous form transport path. Any bulge or buckle caused by a paper jam and forming in the continuous form at any position between the fixing unit and tractor, and across the width of the form, is detected as the swing arm is pushed up at some point along its length, moving the finger away from a sensor monitored by a controller. Printing in the printer is stopped when the sensor detects that the finger has been moved.

Abstract: This invention relates to an apparatus for interrupting the rotary movement of a drive roller for feeding a textile web and comprises a pivoted lever having a frame at one end with an opening through which passes the web driven by the roller. Positioned beneath the opening in the frame is a ring nozzle supplied with liquid under pressure to advance the web passing through the opening in the frame through a guide tube associated with the nozzle. A magnetic switch is provided in circuit with the drive means for the roller to effect stoppage of the rotation of the roller when the switch is actuated, a linkage being connected between the lever and the switch to actuate the latter when the lever is pivoted.
