  • the straight stocks are reduced by each of the rollers 5, 6, and 7 to be bent in the laying head H direction.
  • the thin straight stocks to run at high speed tend to swing up and down or right and left during running, and therefore the center guide 17 has a role of helping the above-described straight stocks passing through the inside of the guide unit 2 to run straight to make directing and reduction by the rollers 5, 6, and 7 secure.
  • the first bend forming roller guide G11 illustrated in FIG. 2 to FIG. 4 is provided with roller eccentricity adjusting mechanisms 12 for adjusting positions (reduction positions) of the rollers 5, 6, and 7 respectively.
  • the eccentricity adjusting mechanisms 12 each include: the gear wheel 10; the eccentric piece 11; a pinion shaft 13; and a pinion 14.

  • the other second bend forming roller guide G12 in the first guidance equipment G1 is disposed adjacently to the one first bend forming roller guide G11 on the downstream side thereof (right side in FIG. 1 ) with a space left therebetween.
  • the constitution of the second bend forming roller guide G12 is the same as that of the first bend forming roller guide G11. For this reason, as for reference numerals and symbols denoting components of the second bend forming roller guide G12 common to those of the first bend forming roller guide G11, the reference numerals and symbols used during the explanation of the first bend forming roller guide are used as they are.
  • the difference of the second bend forming roller guide G12 from the first bend forming roller guide G11 is that as illustrated in FIG. 1 , the second bend forming roller guide is half rotated (rotated by 180° clockwise) from the first bend forming roller guide to be mounted on the base plate 1. For this reason, dispositions of the components of the second bend forming roller guide G12 are positioned in an inverted manner from the first bend forming roller guide G11. As a result, of the second bend forming roller guide G12, two rollers 5 and 6 are disposed on the lower side in FIG. 1 and a single roller 7 is disposed on the upper side in the same drawing.
  • the first guidance equipment G1 enables smooth guiding to the laying head in a manner that the first and second bend forming roller guides G11 and G12 having the same constitution are aligned contiguously on the base plate 1 (bed plate 1a) so as to be inverted to each other and are adjacently disposed in a form in which the combination of the two upper rollers 5 and 6 and the single lower roller 7 and the inverted combination (combination of the single upper roller 7 and the two lower rollers 5 and 6) are one set and a curvature enabling the straight stocks to bend in the laying head H direction is made.

  • first and second directing roller guides G21 and G22 are the same as that of the above-described first and second bend forming roller guides G11 and G12. For this reason, as for reference numerals and symbols denoting components of the first and second directing roller guides G21 and G22 common to those of the first and second bend forming roller guides G11 and G12, the reference numerals and symbols used during the explanation of the first and second bend forming roller guides G11 and G12 are used as they are.
  • the difference lies in disposition positions of the first and second directing roller guides G21 and G22 that are provided contiguously.
  • the first guidance equipment G1 and the second guidance equipment G2 are different in that the first and second bend forming roller guides G11 and G12 placed on the left side in FIG. 1 are in a state inverted to each other, while each of both the first and second directing roller guides G21 and G22 includes rollers 5 and 6 positioned on the upper side and a roller 7 positioned on the lower side and therefore the first and second directing roller guides G21 and G22 are not in an inverted state.
  • first directing roller guide G21 and second bend forming roller guide G12 The relationship between the adjacent first directing roller guide G21 and second bend forming roller guide G12 is that the roller 7 of the one first directing roller guide (right in FIG. 1 ) is positioned on the lower side and the roller 7 of the other second bend forming roller guide (left) is positioned on the upper side, resulting in that the second bend forming roller guide G12 is mounted on the base plate 1 so as to be inverted.
  • the first and second directing roller guides G21 and G22 can direct the straight stocks passing through the center guide 17 by their upper rollers 5 and 6 and their lower rollers 7.

  • the third guidance equipment G3 is contiguous to the above-described second guidance equipment G2 on the downstream side thereof, and includes a plurality of bend-back forming roller guides (two bend-back forming roller guides G31 and G32 in the illustrated example) for bending back the above-described straight stocks to make the guiding to the laying head H smooth.
  • the first and second bend-back forming roller guides G31 and G32 achieve the guiding of the above-described straight stocks to the laying head H, and have a function for bending back the above-described straight stocks being guided in a bent state and forming them linearly in order to make the guiding to the laying head smooth.
  • the first and second bend-back forming roller guides G31 and G32 constituting the third guidance equipment G3 have a function to linearly form the straight stocks running while being guided by the second guidance equipment G2 in a bent state in order to prevent the straight stocks from running directly toward the laying head H direction and coming into contact with a quill pipe Ha being a guiding pipe in the laying head.
  • Each constitution of the first and second bend-back forming roller guides G31 and G32 is the same as that of the first and second bend forming roller guides G11 and G12. For this reason, as for reference numerals and symbols denoting components of the first and second bend-back forming roller guides G31 and G32 common to those of the first and second bend forming roller guides G11 and G12, the reference numerals and symbols used during the explanation of the first and second bend forming roller guides are used as they are.
  • the first guidance equipment G1 and the third guidance equipment G3 are different in that the first bend forming roller guide G11 has a combination of the two upper rollers 5 and 6 and the single lower roller 7, while the first bend-back forming roller guide G31 has a combination of the single upper roller 7 and the two lower rollers 5 and 6. Then, the first guidance equipment G1 and the third guidance equipment G3 are different in that the second bend forming roller guide G12 has a combination of the single upper roller 7 and the two lower rollers 5 and 6, while the second bend-back forming roller guide G32 has a combination of the two upper rollers 5 and 6 and the single lower roller 7.
  • first and second bend-back forming roller guides G31 and G32 are different from the first bend forming roller guide in that the first and second bend-back forming roller guides G31 and G32 are each inclined by a predetermined angle toward the clockwise side in FIG. 1 relative to the first bend forming roller guide G11 to be mounted on the bed plate 1a.
  • the dispositions of the rollers 5, 6, and 7 of the first bend-back forming roller guide G31 are in a state inverted to those of the rollers 5, 6, and 7 of the second directing roller guide G22 adjacent on the upstream side (left side in FIG. 1 ).
  • the first and second bend-back forming roller guides G31 and G32 with their combinations of the rollers 5, 6, and 7 being inverted to each other are disposed contiguously, and in order to prevent the bent straight stocks guided by the second guidance equipment G2 from proceeding according to the curvature, the rollers of respective groups of the first and second bend-back forming roller guides bend back the straight stocks in the laying head H direction and correct them straight to smoothly guide them to the quill pipe Ha in the laying head H along the straight line.
