  • Patent number: 12060675
    Abstract: The present disclosure relates to a clothes folding device including: a loading assembly which causes the clothes to be pushed-in and seats the clothes on a first folding layer equipped with a conveyor for transport; a folding assembly which performs the folding of the clothes while the pushed-in clothes are transported; and an unloading assembly which is disposed below the folding assembly and loads the clothes discharged by the folding assembly. The loading assembly includes: a seating plate which forms an inclined surface at an inlet and allows the clothes to be seated thereon; a clamp assembly which fixes the clothes and moves the clothes to the first folding layer; and a transport roller which presses the clothes seated on the first folding layer and rotates together with the moving of the clothes while pressing the clothes, and thus, preventing the clothes from being separated. The clamp assembly includes a wheel assembly and a clamp plate which presses inserted clothes from both sides.

  • Patent number: 11891263
    Abstract: An interfolding machine produces interfolded sheets according to an interfolding configuration and, starting from a web of paper provides a feeding section, which applies a tension on the web and moves the same along a feeding direction feeding the same to a cutting section, in which the web of paper is cut into a series of sheets at a cutting point between a cutting roller and a counter-cutting element. Downstream of the cutting section, a folding section includes a first and a second folding rollers counter-rotating with respect to each other. The first and second folding rollers rotate about respective rotation axes with a first peripheral velocity vP, and fold, at a folding zone, a plurality of sheets in a plurality of panels and form the stack of interfolded sheets. The cutting roller alternately distributes the aforementioned sheets between a transfer roller and the first folding roller.

For example, the mechanism may include a first facial toothing on an interior face of the torque preloading element and a second facial toothing on an exterior face of an opposing element. The opposing element is mounted to a work side end of the cylinder and the first facial toothing engages the second facial toothing.

  • Patent number: 5860342
    Abstract: Point needles in a conveying cylinder of a rotary press are caused to follow a curve course which securely fastens a web to the cylinder while eliminating transport damage to the printed products as well as reducing paper waste. The needle tips of the point needles are moved along their path by the superimpositioning of two pivot movements, one of which is accomplished by a point holder arm and the second of which is accomplished by a rocker. The two cooperate to form a level four member swivel joint.

  • Patent number: 5741209
    Abstract: The folding blade spindle of a folding drum is rotatably driven by a single drive train that utilizes only one gear drive pair. The folding drum itself is rotated by a separate drive assembly. The use of only one gear drive pair for the folding blade spindle drive substantially reduces play in the folding blade and promotes accurate folding of printed products.

  • Patent number: 5707330
    Abstract: The present invention provides an apparatus for producing at least two 4-page signatures (340) and an apparatus for producing at least one 16-page signature (460). The signatures are produced by folding and cutting sheets cut from a continuous web in a folding machine (500 or 600). The apparatus of the present invention provides a selectable blade device which folds or folds and cuts sheets being processed in the device. When placed in the fold and cut position, the apparatus is capable of producing at least two 4-page signatures (340) or at least one 16-page signature (460) without the need for a final off-line trimming step.

  • Patent number: 5647524
    Abstract: A tearing-off roller pair, for tearing off sections or strips divided by perforation cuts from a material web, consists of a first roller with a substantially smooth steel shell and, applied against it, a second roller with a resilient body set into it for increasing the contact pressure, which resilient body projects above its peripheral surface in its unstressed state. To allow a greater retaining force to be exerted on the sections to be torn off, several of the resilient bodies are set in a recess along a cylindrical surface of the second roller.

    Abstract: An imaging device is provided utilizing a continuous-form recording sheet (i.e., continuous-form sheeting), having a plurality of transverse perforations at predetermined intervals of length, on which the desired image is formed. At least an oscillating member which is driven by a rotating shaft is provided for oscillating continuous-form sheeting discharged from the imaging device. The oscillation caused by the oscillating member forwardly propagates the sheeting toward the imaging device. The continuous-form sheet is alternately and accurately folded at the transverse perforations in opposite directions, and stacked in a vertical direction between two folding positions as the continuous-form sheeting is discharged from the imaging device.

    Abstract: To provide close coupling between movable elements, such as segments (18) capable of varying the effective diameter of a folding blade cylinder (2) or a movable jaw (38) of a folding jaw cylinder, a first gear gear element (21, 47) is coupled via a positioning spindle (20, 43) to the respective movable element (18, 38); a second gear element (22) is coupled to the spindle (20, 43) and further rotationally coupled to the cylinder shaft (11, 35). A positioning or adjustment gearing, for example a differential, or a planetary gearing is positioned in close vicinity to a side wall of the machine, facing the respective cylinder, the positioning gearing being operable to be controlled to change the relative angular relationship between input or received rotation and output or delivered rotation, and being coupled to the second gear element (22), to receive rotation therefrom and further to the first gear element to deliver rotation and additional adjustment movement thereto.

  • Patent number: 5096175
    Abstract: To move folding jaws (4, 5) in a scissor-like or pincer-like movement symmetrical with respect to a center line (CL) and to permit adjustment of the gap or opening of the jaws, for acceptance of folded substrates of different thicknesses, the jaws are coupled together by a rotation reversal arrangement (14, 114, 112, 314) so that rotation of one of the carrier bodies (6) will be transferred as an equal and opposite movement to the other (7) of the carrier bodies. An axial position adjustment spindle (25, 125, 325), controllable by a hand wheel (29) or servo motor (30), changes the axial position of gears rotating or rotating with a shaft (2, 202, 402) of a folding jaw cylinder (1, 201, 401), at least some of the gears or gear pairs having inclined teeth, to thereby transfer a positioning movement into a relative rotary shift of the respectively rotating gear with respect to the gear driving the shaft, thereby causing rocking or tilting of the folding jaw carriers (6, 7).
