摘要： A liquid ejection apparatus includes a conveying unit, a winding unit, a printing unit, and a rotation control unit. The conveying unit is configured to intermittently convey a printing medium by a predetermined feed amount. The winding unit is configured to wind the printing medium conveyed by the conveying unit. The printing unit is configured to perform printing on the conveyed printing medium. The rotation control unit is configured to control the winding unit to rotate in a winding direction at a predetermined timing after the conveying unit has started to convey the printing medium intermittently, and then cause the winding unit to rotate in a reverse direction opposite to the winding direction.

摘要： The invention relates to an improved blowing nozzle, in particular for stretching systems, which is characterised by the following features, inter alia: the nozzle box (5) is divided in its longitudinal direction (L) into at least two regions, specifically a first longitudinal region (LB1) closer to the inflow side (7) and a second longitudinal region (LB2) that is subsequent and/or downstream and/or further away from the inflow side (7), the first longitudinal region (LB1) is convergent or comprises at least one convergent portion in which the height (H) between the lower face (11) and the upper face (15) is smaller than the height (H1) in the region of the inflow side (7) as the distance from the inflow side (7) increases, and the second longitudinal region (LB2) is divergent or comprises at least one divergent portion in which the height (H) between the lower face (11) and the upper face (15) is greater than the height (H) at the end of the first longitudinal region (LB1) and/or at the beginning of the second longitudinal region (LB2) as the distance from the inflow side (7) increases.

摘要： A tensioning control device having a first motor that applies a torque to a first end of a substrate in a first direction and a second motor that applies a torque to a second end of the substrate in a second direction that is generally opposite the first direction is disclosed. In this manner, the first motor and the second motor apply torque to the substrate in opposing directions, thereby placing the substrate in tension. In one embodiment, the first motor applies a torque to the first end of the substrate that is equal to the torque applied to the second end of the substrate by the second motor. By placing the substrate in tension in this manner, an actuator is able to incrementally move the substrate in a forward direction and a backward direction independent of the tension applied to the substrate.

摘要： 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.

摘要： The invention provides a paper conveyance mechanism capable of curl correction of paper drawn out from roll paper according to the intensity of curl. The paper conveyance mechanism comprises an ironing part for correcting paper curl which is brought into contact with an outer surface of the paper, a pressing part which presses the paper from one side to bend the paper at the ironing part, and an arm engaged with an outer circumferential surface of the roll paper to be operated according to a change in a roll diameter. An upstream-side pressing part is moved from the one side toward the other side in association with an operation of the arm during at least part of a period of the operation of the arm to reduce an ironing angle formed in the paper bent at the ironing part according to a decrease in the roll diameter.

摘要： A device for inserting a web of printing material into a flat-bed die-cutting and/or embossing machine includes a compensator for converting a continuous movement of the web of printing material into an iterative movement of the web of printing material. A clamping unit clamps the web of printing material, a cutting unit carries out a cross cut through the web of printing material, and an inserting unit transports the web of printing material into the flat-bed die-cutting and/or embossing machine. The device advantageously allows the web of printing material to be automatically clamped, cut and fed to the flat-bed die-cutting and/or embossing machine. As a result, no further stopping of an upstream printing press is required and the amount of waste is reduced. A manufacturing system for producing packages and a method for feeding a web of printing material are also provided.

摘要： Described herein are methods and systems for minimizing folding defects when rolling a paper product. The method comprises rotating a roll in a manner that draws a paper product toward the roll. The location of a pick-up point between the roll and the paper product is altered by influencing the air pressure experienced by the paper product. This may be accomplished by flowing air in one of several manners described in the specification.

摘要： A slitter device includes a first tension detecting unit for obtaining a raw-cloth tension value which is a tension value of a sheet material fed out from a let-off mechanism, a second tension detecting unit for obtaining a divided material tension value which is the sum of the tension values of each of divided sheet materials, and a drive control device which includes a comparator to which the first tension detecting unit and the second tension detecting unit are connected, and which compares the raw-cloth tension value and the divided material tension value with each other; and a drive controller which controls an operating state of a roll driving motor such that the raw-cloth tension value and the divided material tension value coincide or substantially coincide with each other based on the comparison result of the comparator.
