Definitions

  • the design of the cam track 23 is-such' as first to retract and then advance the feed table i l in proper timedrelation in the cy cle of themachinei;
  • the adjusting movement .j of the auxiliary frame 32 moves the cam shaft 50 slightly with respect to the cam disk 26, but not sufliciently to disturb the timing of the cam- .operated parts therein.
  • rand strip prises an elongated arm forkedat its rear end and pivotally supported upon a transverse pin 82 which extends between the side members of the feed carriage 42 in'alignment with and beneath the slot or opening in thefeed table 44.
  • a torsion spring 84 surrounds the pin 82.and tends normally to elevate the free end of the spreader into the position shown in Figs. 1 and 2, wherein it isv positioned midway between the two bending devices.
  • the intermediate portion of the spreader is reduced in thickness and at its free. end it is provided with two downwardly extending deflecting surfaces 81' which act to engage the inner marginal edges of the sides of the bent rand as the latter is drawn from between'the bending device by the forming rolls 14 and'22.
  • a bending device for a rand forming machine comprising a bendingplate havingan edge face for deflecting one side of a rand strip and an upwardly projecting portion adjacent thereto, a presser member pivotally mounted at the outer edge of the bending plate, overlying the projecting portion thereof and. having a rand-gripping face extending beyond the randengaging face of the bending plate, and spring means for holding said presser member in contact with the projecting portion of the bending plate.
  • a rand forming machine comprising cooperating rolls, a feed table movable toward and from the rolls, spaced bending devices carried by the table, means for doubling a rand'strip between the bending devices, and a spreader movable automatically into position between the sides of the bent rand during the advancing fmojvement of the feed table.
