  • Grippers adjacent the heelward portions of the insole forepart grip adjacent marginal portions of the upper and move downwardly and twistingly of a last over which the upper is positioned to tension the upper about the last.
  • a control responsive to a left or right shoe orientation of the machine then causes only one of the grippers at the inside of the right or left shoe to additionally move inwardly and then upwardly relative to the last to further position and tension the upper.
  • This invention relates generally to shoe upper forming machines and, more particularly, to a machine for performing a pulling and lasting operation in the entire forepart region of the shoe.
  • a cement applying plate having a surface conforming to the shape of the insole on the last in both the peripheral outline of the insole and the surface or planar configuration of the insole on the last was later added to the machine.
  • the conformed surface of the insole engaging plate was positioned to have its insole engaging surface parallel to the insole at each point corresponding to the insole on the last.
  • the plate was then removed toward the insole simultaneously to engage the insole over the entire insole engaging surface of the plate.
  • a single channel formed about peripheral portions of the insole engaging surface and having an open side in the surface was then supplied with cement to form a bead of cement about the peripheral portions of the insole engaged with the open side of the channel.
  • the cement applying plate was then withdrawn and wipers engaged marginal portions of the upper with the adhesive bead on the marginal portions of the insole to secure the upper to the insole.
  • a machine for pulling and lasting a shoe upper about a last is provided with a pair of grippers for engaging inside and outside marginal portions of an upper in a heelward portion of the shoe forepart having different operative movements for tensioning the upper about a last over which it is positioned according to the differing inside and outside curvatures of the corresponding portion' of the last.
  • a control preferably responsive to a left or right position of a shoe heel rest of the machine indicative of the relative inside and outside curvatures of left and right shoes, controls the differing gripper movement.
  • Means act on a flexible wiper of the machine to conform the wiper to the differing planar curvatures of the heelward portion of the insole forepart to improve wiping of the upper against the insole in this heelward portion.

  • the machine is gener- 3 ally similar to that disclosed in the above identified U.S. Pat. No. 3,099,846.
  • the grippers generally designated at 8 and commonly called the No. 2 forepart grippers are similar in construction and function to those described in the above identified copending patent application.
  • these grippers are designed to draw the upper downwardly over a last on which the upper is positioned, inwardly of the last, and to twist the upper into conformity with a peripheral curvature of an insole on the last, all in the heelward portion of the forepart of the upper.
  • both grippers generally designated 8 do not perform all these motions in the forming of a single shoe upper, as is explained below. Further distinctions from the machine of the above patent and application will also be described.
  • this embodiment has a heel support variably positioned for receiving right or left shoes and thereby indicating the side of the inside or outside curvatures of the shoe. Cement is applied to the insole. The grippers then tension the upper over the last using different movements on the differing inside and outside peripheral curvatures of the shoe. The wipers then wipe marginal portions of the upper against corresponding marginal portions of the insole including at the asymmetrical planar curvature of the heelward portion of the insole forepart.
  • FIG. 1 shows the heel support 28 mounted on a member 30 having a pivot lug at each end received in a U- shaped member 32.
  • the pivotal connection of the members 30 and 32 may be by receipt of the lugs of the member 30 in a U-shaped boss in the member 32 with the lugs retained in the boss by a bolt 34 projecting through the ends of the boss.
  • a number of such U-shaped bosses may be vertically disposed along the end of the member 32 to provide heightwise adjustment of the heel support relative to a shoe on a last 'L positioned in the machine on a portion of the shoe support 2.
  • the member 32 is slidingly supported by a bolt 35 extending through a slot in a member 36.
  • Springs 38 are stretched between lugs of the member 32 and lugs of the member 36 to urge the member upwardly until the bolt 35 engages a movable shaft 40 of a diaphragm thruster 42 (not shown in FIG. 1).
  • the wipers engage the shoe, as later explained, they impart a heelward force to the shoe which may dislodge it from the heel support.
  • the thruster 42 is simultaneously activated with the wipers to drive the shaft 40 downwardly, carrying with it the abutting bolt 35 and connected heel support 28. The added force of the thruster retains the shoe firmly in the heel support.
  • the member 36 has a T-headed portion slidingly received in an undercut channel of a member 46 for sliding movement normal to the plane of FIG. 3 or transverse to the last L in the machine.
  • a spring loaded friction member 48 normally holds the member 46 against such sliding movement, except as urged by a doubleacting piston and cylinder 50 the movable piston of which is connected through pivoted lever 52 to a post 54 of the member 36 extending through a slot in the channeled member 46.
  • the member 46 is slidably mounted in a frame 56 of the machine to which a piston of a piston and cylinder combination (not shown) carried by the member 46 is connected for sliding the member 46 relative to the frame and lengthwise of the last.
  • a pair of stops 56 are seen to be positioned on either side of the pivoted lever 52 for limiting movement of the lever.
  • a control is effective to cause the piston and cylinder 50 to drive the lever 52 into engagement with one or the other of the stops 56 in each operative position of the machine.
  • the control alternates the lever between engagement with each stop.
  • the heel support 28 operatively connected to the lever 52 is shifted alternately between a left and right position for operating alternately on left and right shoes, respectively.
  • a switch may be provided for controlling the piston and cylinder 50 to its left or right shoe condition.
  • FIGS. 1 and 3 also show another U-shaped member 60 having roller insole engaging members 62 on tines of the U and receiving a pivot shaft 64 through a bridge of the U between the tines.
  • the U-shaped member 60 freely rotates on the shaft 64.

  • the rollers 62 are oriented below the plane of the wipers l2, and below the heelward portion of the forepart of a shoe on the last L located in the machine. After the grippers have tensioned the upper about the last and a cement applying surface of a cement applying plate 72 (FIG.
  • the wipers 12 move heelward of the last at least to the heelward portion of the forepart and close inwardly of the last to wipe marginal portions of the upper against marginal portions of the insole in the well known manner.
  • the insole departs from its generally planar orientation in the toe region and curves upwardly as seen in FIG. 3.
  • the planar curvature of the insole often is different or asymmetrical from the inside to the outside sides of the insole.
  • the curvature changes from one style of shoe to the next. Accordingly, no one orientation of the wipers appropriate for the planar curvature may be made for accommodating even a single pair of shoes let alone different shoe styles.
  • the piston and cylinder 66 pivots the lever 65 to raise the rollers 62 at the opposite end of the lever into engagement with the wipers to bend the wipers into engagement with the insole.
  • the U-shaped member 60 pivots on the shaft 64 to continue bending the other, usually inside, wiper into engagement with the insole. This pivoting movement of the member 60 equalizes the pressure of the wipers on the inside and outside of the shoe to uniformly press marginal portions of the upper on both sides of the shoe against the insole.
  • each wiper 12 is provided with a slot 74 (FIG. l) extending into the wiper from the portion engaging the heelward portion of the insole forepart a grippers 8.
  • FIG. 4 illustrates one of the two identical such grippers.
  • a gripper member 80 is fixedly mounted on a body member 82 and a second gripper member 84 pivoted on the body member for gripping amarginal portion of the upper between the gripper members 80 and 84.
  • the pivoted gripper member 84 is operatively connected to a piston and cylinder 86 in the body of the gripper for pivotal movement toward and away from the gripper member 80.
  • the body member 82 is pivotally mounted on a frame 88 of the machine by a link 90 pivotally connected at each end to the frame and the body member.
  • a bell crank 92 pivotally connects the body member to two pistons and cylinders 94 and 96.
  • a further piston and cylinder 97 swings the gripper normal to the plane of FIGS. 4 and 5 as described in the copending application.
  • the piston and cylinder 86 In operation of the gripper 8 the piston and cylinder 86 first operates to grip a marginal portion of the upper between the gripper members 80 and 84.
  • the piston and cylinder 94 then operates to raise the connected end of the gripper body 82 while retaining the bell crank 92 in the position relative to the body member shown in FIG. 4.
  • the gripper members at the opposite end of the body member then move downwardly as seen in FIG. 5.
  • the piston and cylinder 96 may then be extended to swing the bell crank 92 from the position shown in FIG. 4 to the position shown in FIG. 5.
  • the pivotal movement of the bell crank 92 drives the body member and connected gripping members 86 and 84 to the left as seen in FIG. 5, inwardly of the last.
  • a twisting action as described in the above recited copending patent application may also occur.
  • the gripper members 80 and 84 may be raised toward the underside of the last by a slight cooperative retraction of the pistons and cylinders 94 and 96 while retaining the relative orientation of the bell crank 92 to maintain the gripping members 80 and 84 in their inward position.
  • Such raising of the gripper members 80 and 84 presses the marginal portion of the upper against the insole on the last in a wiper-like action to enhance the pressing of the upper against the insole with the gripping members 80 and 84.
  • the gripping member 84 is provided with an extended, substantially flat surface 98 substantially parallel to the insole on the last when the grippers are in their innermost extended position.
  • only one of the grippers 8 preferably carries out the above described sequence of movements.
  • the other gripper merely grips the upper and moves downwardly of the last by action of the cylinder 94, the bell crank 92 then being in the orientation relative to the body member 82 shown in FIG. 4. Twisting movement of the grippers may be carried out by either or both of the grippers, again as recited in the above identified patent application.
  • the outside planar curvature of an insole in the heelward portion of a shoe forepart is small as compared to the planar curvature of the inside side of the heelward portion of a shoe forepart. Accordingly, it is preferably desirable to have the gripper 8 on the inside side of a shoe carry out the complete sequence of gripping, downward, inward, twisting and upward movements, thereby pressing the upper against the more curved heelward portion of the forepart insole which curve brings the insole substantially above the general plane of the toe portion of the insole.
  • the gripper 8 adjacent the outside side of the shoe preferably grips the upper and moves only downwardly and twistingly to draw the upper toward the outside heelward portion of the shoe forepart less curved out of the toe plane of the insole than the inside.
