  • FIG. 1 a double facer machine designated generally as for making double-faced corrugated paperboard.
  • the machine 10 includes an endless belt 12 extending around rollers 14 and l4one of which is driven.
  • the corrugated paperboard is designated as 16, and is pulled through the machine 10 by means of the belt 12 while in contact with the upper surface of a plurality of variable heat platens 18, 20, etc.
  • the platen 18 has an upper surface 19 adapted to be in intimate contact with the paperboard 16 so that heat may be transferred from the platen 18 to the paperboard 16 to effect'an adhesive juncture betweenthe liner and the single-faced paperboard.
  • the machine 10 includes side frames 22 and 24 which support the platen 18.
  • the platen 18 may reciprocate vertically when moving from a position having maximum surface contact with the paperboard 16 as shown in FIG. 3 to a position having minimum surface contact with the paperboard 16 as shown in FIG. 4.
  • the platen I8 is preferably moved from the position shown in FIG. 3 to the position shown in FIG. 4 by a tilting action, whereby the downstream end of the platens will have slightly more than line contact with the paperboard 16 and thereby prevent the web of paperboard 16 from drooping.
  • the tilting or pivoting action is attained by means of a cylinder 30 pivotably supported at its lower end on a suitable brace or bracket.
  • a piston 28 extends from the cylinder 30 and has its free end pivotably connected to the upstream end of the platen l8.
  • Conduits are provided for introducing a motive fluid such as pressurized air into the cylinder 30 to effect tilting of the platen 18 from the position shown in FIG. 3 to the position shown in FIG. 4 and vice versa.
  • the downstream end of the platen 18 is provided with a cradle 33 supported by pins 32 and 34 which extend inwardly from the side frames 22 and 24 respectively. See FIGS. 2 and 3.
  • Adjacent the upper surface 19, the platen I8 is provided with a lug 36 on one side and a lug 38 on the opposite side. See FIG. 2.
  • the lugs 36 and 38 extend outwardly and transversely with respect to the platen 18.
  • a lever 40 is pivotably supported intermediate its ends by means of a pin 42 supported by the side frame 22.
  • a lever 44 is supported on the opposite side of platen 18 intermediate its ends by means of a pin 43 on the side frame 24.
  • the lever 40 is below lug 36 so that lever end 46 may contact lug 36.
  • lever 44 is supported so that one of its ends may contact lug 38.
  • lever 40 which is designated as 48 is disposed above the lever end 46 and adjacent the plane of upper surface 19 on platen 18.
  • a pair of rails 50 and 52 are supported from the side frames 22 and 24 or any other convenient support structure by means, not shown.
  • the rails 50 and 52 are above the lower run of the belt 12 as will be apparent from the figures of the drawing.
  • Transversely aligned links 54 and 56 have their upper ends pivotably secured to the rails 50 and 52 by pins 58 and 60, respectively.
  • the links 54 and 56 rotatably support a ballast roll 26.
  • the axis of rotation of ballast roll 26 is longitudinally offset with respect to the longitudinal axis of pins 58 and 60. See FIG. 3.
  • a pair of transversely aligned links 62 Downstream from the links 54 and 56, there is provided a pair of transversely aligned links 62, only one of which is shown.
  • An adjustable bolt or stud 66 on end 55 of link 54 is in contact with one of the links 62.
  • the links 62 are pivotably supported by the rails 50 and 52 by means of pins 63 and are parallel to links 54 and 56.
  • the links 62 rotatably support a ballast roll 26' which contacts the lower run of belt 12 in the same manner as roll 26.
  • the links 64 are rotatably supported from the rails 50 and 52 by means of pins 65 and are parallel to links 62.
  • the links 64 rotatably support a ballast roll 26" which contacts the lower run of belt 12 adjacent the vertical plane containing pins 32 and 34. Roll 26" may be raised by manually actuating exten sion 68 on link 64.
  • the manner in which a double facer machine is utilized is well known to those skilled in the art and need not be described in detail.
  • the platens may be heated in any conventional manner such as by electrical heating coils or introducing steam into the platens. During normal operation, the elements assume the relationship illustrated in FIG. 3.
  • the platens When it is desired to minimize heat transfer from the platens to the paperboard 16, such as when the machine has stopped and scorching is to be avoided, the platens may be moved downwardly away from the paperboard so as to assume the relationship shown in FIG. 4. In FIGJ4, the platen 18 has minimum contact with the paperboard 12 so as to prevent drooping of the same, but little heat transfer take place.
  • Each of the platens is individually operable whereby the number of platens moved from a position as illustrated in FIG. 3 to the position illustrated in FIG. 4 may be selectively arranged as desired.
  • a double facer machine comprising a plurality of aligned heated platens each having an upper surface for contact with a web of paperboard, an endless belt above said surfaces for moving the paperboard across said surfaces, at least two ballast rolls supported above the lower run of the belt and in contact with the lower run of the belt, said platens being mounted for downward movement away from the paperboard to decrease heat transfer to the paperboard, and means for automatically moving at least one of the ballast rolls upwardly in response to the downward movement of at least one of the platens which is adjacent said roll.
  • each ballast roll is supported by a pair of links pivotably supported above the lower run of the belt.
  • said automatic means includes at least one lever supported to engage a lower end portion of one of said links, and a surface on said one platen for causing movement of said lever to effect upward movement of the ballast roll.
  • each ballast roll is supported by a pair of linksdisposed at an acute angle and pivotably supported above said one platen, and means on one of the links for. moving the adjacent link in the same direction at the same time.
  • a double facer machine comprising a plurality of aligned heated platens each having an upper surface for contact with paperboard, an endless belt above said surfaces for moving the paperboard across said surfaces, at least two ballast rolls supported above each of the platens and in contact with the lower run of the belt, said platens being mounted for pivotable movement downwardly away from the plane of the paperboard to decrease heat transfer to the paperboard, and means for automatically moving said ballast rolls upwardly away from contact with the lower run of the belt in response to downward pivotable movement of said platens, said automatic means including lugs on opposite sides of each platen, a separate link pivotably supported by a frame member adjacent each lug, a pivotable link supporting each end of each ballast roll, the links supporting one of the ballast rolls having lower end portions juxtaposed to and aligned with a separate one of said levers.
  • a method of controlling heat transfer to paperboard as the paperboard is processed by a double facer machine comprising the steps of introducing heat into paperboard by causing the paperboard web to contact the upper surfaces of aligned heated platens, moving the paperboard across said surfaces by an endless belt, maintaining the paperboard in intimate contact with said surfaces by means of at least two parallel transversely extending ballast rolls engaging the lower run of the belt, and selectively reducing heat transfer to a substantial extent from said platens to said paperboard by moving selected ones of said platens downwardly away from the paperboard while simultaneously moving the ballast rolls associated with the selected platens upwardly out of contact with the lower run of said belt in response to said downward movement of the platens.
