Definitions

  • the present invention relates to apparatus for drying coated tapes, in particular tapes coated with a pressuresensitive adhesive coating.
  • apparatus for drying coated tapes in particular tapes coated with a pressuresensitive adhesive coating.
  • rotary dryers on which the tape is wound in a series of radially spaced turns.
  • dryers of this type consist of two groups of radial arms which are fixed on axially spaced hubs keyed on a shaft, a drum being formed between the said hubs at the inner end of the arms.
  • the radial arms thus disposed in pairs are formed with apertures which are designed to receive the ends of axially extending spacer bars which are placed in position as the arms rotate, the bars serving to space radially apart successive turns of the tape, by the radial distance between adjacent bars on a given pair of arms.
  • the tape When the tape is dry it is wound on a reel and the two groups of arms rotate together in the opposite direction from when the tape was wound on, and, as it is thus rotated, the spacer bars are removed successively from their associated pairs of arms as soon as the tape has left them.
  • vapours are evolved which may be harmful, so that it becomes necessary for the operator to wear a respiratory mask and to subject himself to a regular medical check-up.
  • each pair of arms travelling adjacent the outlet of the magazine will receive a spacer bar which is immediately and automatically transferred from its waiting position to a position within the arms in which it rolls under the force of gravity either as tar as the hub at the commencement of operations or on to a further previously-engaged bar.
  • the wheel is driven in the direction ⁇ opposite to that of the preceding rotation, for example by means of the winding-up reel of the tape.
  • FIGURE 1 shows, diagrammatically and in perspective
  • FIGURE 2 is a side elevation of the said device
  • FIGURE 3 shows in perspective, a fragmentary view drawn to a larger scale, of the outlet of the magazine bars
  • FIGURE 4 is a View showing, in greater detail, how a pair of arms are tted on a wheel.
  • FIGURE 5 is a cross-section through the said arm along the line V-V of FIGURE 4.
  • FIGURES 1 and 2 The embodiment of apparatus illustrated in FIGURES 1 and 2, comprises a drying wheel 5 keyed on a shaft 6 adapted to be driven in rotation by means (not shown), a magazine 7 providing a downwardly inclined travel path for the spacer bars 8 travelling towards the wheel 5 and also a re-cycling assembly 9 comprising a re-entry ramp 10 and a raising ramp 11 ending at the upper portion of the magazine.
  • the drying wheel consists of two groups of arms 12 and 13, which are radially xed on appropriately spaced hubs 14, keyed on the shaft 6 of the wheel.
  • Each group of arms comprises, in the example illustrated, eight arms extending in a vertical plane, adjacent arms being at 45 with respect to one another.
  • the two groups of arms are connected near their inner ends by means of cross-pieces 15 extending parallel to the wheel pivot.
  • the cross-pieces provide satisfactory rigidity of the assembly and also -form a drum 16 which receives the terminal portion of the tape 17 coming from a reel 18, at which position it has not yet been coated, the coating being effected between the reel and the drying wheel.
  • the arms consist of channel elements 20 of U-shaped cross-section, the open sides of the elements of a pair, facing one another and being positioned opposite one another.
  • elements 20 Within elements 20 are located rails 21 of substantially similar section, the limbs 22, 23 however, having inwardly bent portions 24.
  • the rails 21 terminate adjacent the cross-pieces 15, Whereas the outer ends of the rails terminate at the same level as the elements 20.
  • the arms are provided with hooks 25 the purpose of which will be described later.
  • spacer bars 8 are provided at their respective ends with rollers 26, the diameter of which determines the spacing of the bars on a given one of the arms of the wheel.
  • the diameter of the rollers 26 is slightly smaller than the spacing between the limbs 22 and 23 of the channel section rails 21.
  • the ends of the arms travel in the outlet 27 of the magazine 7, which consists of two metal sections 30, 31, which are appropriately braced and the spacing of which is equal to the length of the bars.
  • the sections 30, 31 are shaped in such manner as to form a downwardly inclined zig-zag path the length of which is sufcient to accommodate at least the total number of bars necessary for equipping the Wheel.
  • the bars are able to travel from the upper portion 32 of the magazine under the influence of gravity, towards the outlet 27 which is disposed in the same horizontal plane as the shaft of the wheel and is provided, at the end of each of the sections 30, 31, with hooks 34, 35. These serve to stop the bars from continuously falling out of the magazine and permit the extraction from the magazine of a bar inthe waiting position.
  • stop pegs 36, 37 adapted to move between a withdrawn position and an operating position wherein they prevent the travel of the bars towards the waiting position.
  • the extractor means or re-entry ramp Disposed below the magazine outlet is the extractor means or re-entry ramp the structure of which is similar to that of the magazine, i.e. it comprises two appropriately cross-braced sections 39, 40.
  • the re-entry ramp is, at its free end portion, provided with hooks 41, 42 similar to the previously mentioned hooks and, furthermore, it is inclined downwardly relatively to the horizontal from the drying wheel.
  • the lower portion of the re-entry ramp 10 is followed by the raising ramp 11 which is formed from sections 44 and 45.
  • Adjacent ramp 11 is the upwardly moving run of an endless belt 46, comprising projecting members, for example studs 47.
  • the upper portion of the belt coincides with the upper portion of the magazine 7.
  • Two retaining straps 48, 49, extending into the wheel, in the immediate vicinity of the arms, are secured at 50 under the re-entry ramp; they pass over a roller 51 disposed above the wheel near their other ends, and are subjected to the action of counterweights 52 which maintain them constantly under tension.
  • the tape 17 (FIGURE 2) is first of all attached to one of the cross-pieces 15.
  • the stop pegs 36, 37 are then withdrawn and the bars 8 slide down in the magazine 7.
  • the wheel With one of the bars waiting at the outlet of the magazine, in the hooks 34, 35, the wheel is rotated in the direction of the arrow F, causing winding-up of the tape.
  • the hooks 25 at the ends of the arms engage the bar 8 carried by hooks 34, 35 and this bar is thus transferred on to a pair of arms.
  • the bar slides in the rails 21 and rolls, due to the force of gravity, towards the centre of the wheel, until it engages the hub or a preceding bar.
  • the arm moves from the position B to the position C the bars are held in position, by gravity, but as they move between the position C and the position D, the arms are downwardly orientated and the bars tend to be rolled out of the arms under gravity.
  • the bars are held in place by the straps 48, 49 until they reach the position D, whereafter the tension in the tape 17 will maintain the bars 8 in place.
  • the spacer bars are no longer maintained in position by the tape and tend to fall under the influence of gravity towards the ends of the arms, but they are maintained in position by the straps 48, 49 until they reach the position C.
  • thetape 17 may be guided so that it is fed to, or withdrawn from the wheel' between the positions B and C. This may be effected by means of suitable guide rolls or by repositioning of the reel 18 at a higher level. The tape itself will then hold the bars in place.
  • Apparatus for drying coated tape comprising an axis; two axially spaced groups of radially extending arms, said groups being rotatable about said axis; radially extending guides on each of said arms; a plurality of spacer bars of a length to engage in one guide of each group of arms; a magazine for containing and feeding said bars; an outlet to said magazine positioned to feed spaced bars from said magazine to the radially outer ends of said arms, as the groups of arms rotate in a first direction, extractor means for removing spacer bars from the guides as the groups rotate in the direction opposite to said first direction and means for returning the bars from the extractor means to the magazine.
  • each arm is provided with a hook at its radially outer end, said hooks extending in said first direction of rotation.
  • said magazine comprises a pair of channel-section rails spaced apart by the same distance as said groups of arms, said rails being disposed in a zig-zag configuration and sloping downwardly towards said magazine outlet.
  • said extractor means includes a pair of downwardly inclinedchannel-section rail members; an upper and a lower end to said rail members positioned in the path of movement of the radially outer ends of said arms, in that lower quadrant of said path of movement in which the arms are moving downwardly as the groups are rotated in said opposite direction.
  • the means for returning the spacer bars to the magazine comprise a connecting pair of channel section rail members, extending from the lower end of the extractor members to the magazine, a driven conveyor belt adjacent said connecting rail members and a set of spaced apart pins extending from said belt between said connecting rail members to engage and transport spacer bars from said lower end to said magazine.
  • a pair of strap means extend substantially tangentially to that lower quadrant of the pair of groups of arms in which the arms are moving downwardly as the groups are rotated in said first direction, said straps serving to retain said bars in said guide rails in such quadrant.
