An image forming apparatus, includes (1) a medium holding unit that holds a recording medium; (2) a guide member configured to be movable, that sets a medium path of the recording medium fed from the medium holding unit as a predetermined path by being locked in a predetermined position, and that is unlocked by a tension of the recording medium; (3) a first conveyance member that is arranged downstream of the medium path of the guide member, and conveys the recording medium; and (4) an image forming unit that forms an image to the recording medium conveyed by the first conveyance member.

A method for protecting a unit for converting a web substrate to limit a jam of the substrate inside the unit, the unit converting the substrate when the unit is stopped, in a packaging production machine: the steps of: detecting at the outlet of the unit that the converted web does not come out; stopping a motor of an infeed arrangement to prevent the substrate from entering the unit; stopping a motor of a feathering drive; and simultaneously stopping the machine, and guiding the substrate to an accumulation storage.

The present invention relates to a web film movement compensating device for a web film movement compensation between continuous forward movement section and intermittent forward movement section comprising two guide rollers (1, 2) rotating freely in stationary positions between a continuous driving device (5) and an intermittent driving device (6), two compensation rollers (3, 4) rotating freely on two respective pivoting arms (7, 8) oscillating about pivot shafts (11, 12), an elastic element (9) connected to one of the pivoting arms to actuate the corresponding compensation roller to move away from the guide rollers, and a movement transmission mechanism including lever arms and transmission rods (13, 14, 15) transmitting an oscillating movement from one of the pivoting arms (7, 8) to the other. A web film (50) moved by the driving devices is supported on the guide rollers (1, 2) and on the compensation rollers (3, 4) forming a meander.

The present invention relates to a flexible package-forming machine for horizontal packaging and method of manufacturing flexible packages. The proposed forming machine consists of an unwinding unit (11), a perforating unit (12), a folding unit (14), a welding unit (16), and a cutting unit (17), wherein a compensating unit (13) is further included intercalated between the perforating unit (12) and the folding unit (14), linking a section with intermittent forward movement (S1) of the flexible band (1) where the flexible band moves in an intermittent manner and including the perforating unit, and a section with continuous forward movement (S2) where the flexible band moves in a continuous manner and including the folding unit, flexible band being accumulated in said compensating unit during the forward movement of the section with intermittent forward movement (S1) and the accumulation being reduced during breaks in the forward movement of the section with intermittent forward movement.

A machining apparatus and method are disclosed, with two blanking devices arranged on a feed path of material for blanking portions of material forming electrode tabs distributed in a step, by varying the period of the working cycles of the two blanking devices independently of one another at each blanking to increase progressively the step between the electrode tabs; the machined material is intended to be wound around a core to produce an electrical energy storage device; the increase in the step between the electrode tabs means that the electrode tabs are aligned on one another in the wound product, taking account of the fact that the dimensions of the product increase during winding.

Computer program product, controller, winding machine and method for winding a winding material from a supply device onto a winding body of a winding machine, wherein the winding material is provided from a supply roller and wound onto the winding body via at least one deflection roller, where an actual winding tension of the winding material is set to a setpoint winding tension depending on a position-dependent compensation signal, stored in a storage unit, to compensate for a changeable free length, resulting from a non-circular cross section of the winding material, of the winding material between the deflection roller and the winding body, whereby due to the fact that the actual winding tension is set to the setpoint winding tension via the position-dependent compensation signal, which is already stored in the storage unit prior to the winding, the computational load for the setting can be reduced.

A system and method is provided that allows for the non-interrupted coating of a pulled substrate with coating materials, even while a coated portion of the substrate is held stationary for cutting. The present invention eliminates waste and improves efficiency and yield, and is particularly applicable to laboratory drawdown coaters.

An assembly for folding polymeric film for machines for forming pouches and the like includes a fixed frame for supporting a magazine for the polymeric film, an element for folding the film that arrives from the magazine, and at least one heat-sealing device for the stable coupling of juxtaposed portions of the folded film that arrives from the folding element. The folding element is mounted on a carriage, which can translate along a respective guide which is integral with the frame, along the sliding direction of the film, with a speed that is variable in intensity and sign. The at least one heat-sealing device acts on portions folded onto themselves of the film during a temporary stop thereof. The carriage retracts with respect to the sliding direction of the film for the entire duration of the temporary stop step provided for the heat-sealing of the film.

An image forming apparatus, including (1) a medium holding unit that holds a recording medium; (2) a guide member configured to be movable, that sets a medium path of the recording medium fed from the medium holding unit as a predetermined path by being locked in a predetermined position, and that is unlocked by a tension of the recording medium; (3) a first conveyance member that is arranged downstream of the medium path of the guide member, and conveys the recording medium; and (4) an image forming unit that forms an image to the recording medium conveyed by the first conveyance member.

A defect detecting device includes a detection unit and a movement mechanism. The detection unit includes a support, an arm supported by the support swingably around a swing shaft, and a sensor for detecting a displacement of the arm relative to the support. The arm includes contactors. The movement mechanism keeps the contactors away from a feed plane during a feed phase of a sheet panel, and moves the contactors to the feed plane and then moves the contactors from the feed plane during a pause phase of the sheet panel. The defect detecting device further includes a determination part configured to determine whether a defect in bag making is present based on data from the sensor.
