Definitions

  • the patent objective is the manufacturing process and equipment for bulky textile formations by vertical layering of fabrics, particularly in the case of fibrous webs from carding machines.
  • the vibration principle consists of fibrous web formation as it leaves a carding machine (or in fact any other fiat textile configuration) to vertical folds by an oscillating saw the amplitude of which is equal to the fold height, while the rotation principle is based on formation of a flat textile formation in vertical folds by its bringing into gaps between cogs of the working cylinder.
  • Concrete design concepts of the vibration principle are well known from, inter alia, CZ P 37619, 56029, 87556, 235494, 263300, 263075 and 284296.
  • the punches (2) can be arranged in in rows under the angle ⁇ in a flexible continuous belt (17) tightened between cylinders (18) & (19) and sloping to the conveyor level (6) under angle ⁇ .
  • the flat textile formation is brought between two rows of punches fixed to the bars moving round the forming body centre line along the track that enables to create space necessary for fold forming in the quadrant I. of the forming body and space of the fold pressing to the required density of bulk material in the quadrant II. of the forming body, while the quadrant I/II interface is gradually created by radial jumping movements of the bars in places of minimum distances between the rotating body surface and the conveyor.
  • the invention principle originates from the idea where the web, or any other flat textile formation (such as needled textiles), is brought by a feeding device (best of all a pane-type) between direct punches fixed to moving bars that form a rotating body of variable diameter.
  • the bars are arranged in a collar to create space necessary to form the folds out of a flat textile material, while moving, at the same time, along a track permitting to fill the space among the bars in the first quadrant and quick exit of fleece at the boundary of first and second quadrants of the rotating body.
  • the punches In filling the space between punches with the flat textile material, the punches establish the vertical direction to the rotating body centre line, the diameter of which increases in this interval to its maximum value.
  • the fleece created in this process leaves the punches at the boundary of first and second quadrants almost by jumping, approximately in a vertical direction to the level of the conveyor removing the bulk layer away, while the diameter of the rotating body drops in this interval to its minimum value.
  • the manufacturing equipment for vertically layered bulky textile products is based upon the principle of having a rotating body of a variable diameter, the surface of which is formed with punches fixed to bars moving in radial grooves of disc fixed to a driving shaft and controlled by cams that influence their radial direction movements.
  • the method and equipment for vertically layered bulky textile products according to this invention improves, in a comparison with already known techniques based on the rotation principle, the layer structure, which results in particularly uniform folds in the whole profile of bulky textile products and elimination of the specific embossing patterns, which improves smoothness qualities of both surfaces. Practically the same effects as with vibration laying techniques is achieved this way, however, the output in question is several times higher so that the equipment can be integrated into high-throughput manufacturing units.
  • the equipment shown in Fig. 1 consists of the fold forming body created by the rotating body (4) with variable diameter, the surface of which is formed by punches (2) fitted into bars (3) guided in radial grooves of rotating grooved discs (7) fixed to the driving shaft (11) and shifted in the direction of grooved disc (7) diameters from the discs centres by cams (8) fixed by the fastener (14) to the frame (15) and shifted to the disc centres (7) by spring elements (9) so that the body (4) diameter increases to its maximal diameter in the first quadrant and decreases to its minimum diameter in the second quadrant.
  • the bar transition from the minimum diameter to the minimum one is made in a jump to the quadrant I/II interface of the body (4).
  • the pane assembly (10) is assigned in the first (I.) quadrant to the body (4), as well as guiding wires (12) and guiding metal sheet (13).
  • the equipment shown in Fig. 2 shows the equipment design differing to the one in Fig. 1 only in the point that movements of bars (3) with punches (2) is actuated by the cam (8), which is designed as a grooved one and fixed to the frame (15) by the fastener(14).
  • the bar (3) movement in the cam (8) groove is derived from grooved disc (7) rotation movements over the swing lever (16) mounted to the disc (7), which is fixed to the driving shaft (11).
  • the equipment can be utilised mainly in the textile industry in manufacturing processes of bulky and thermal insulation / filtration textile materials.
  • the process permits to utilise maximum throughput capacities of fleece-making machines arranged to a manufacturing line.
