Processing method for making column-shaped foam

A second step:

• Said long-shaped square foam positioned on the material-feeding device of a planing machine, said planing machine comprising said material-feeding device and a planing device and a material-delivering device, said planing device provided thereon with a knife base having a plurality of planing knives spaced apart annularly, said planing knives having their planing portions at the outer ends respectively provided at different locations according to the sequence of rotating and planing of said knife base:

A third step:

• Starting said planing equipment to actuate said material-feeding device to push said long-shaped square foam to said planing device at a preset speed, said knife base simultaneously rotating at a preset speed:

A fourth step:

• Said planing knives actuated to carry out planing in sequence, said long-shaped square foam on said planing device contacting first with the first-positioned planing knife, said long-shaped square foam having its peripheral surface planed circularly by the planing portion of said first-positioned planing knife, said long-shaped square foam continuing to be moved forward axially and planed by the other planing knives that are arranged orderly according to their planing sequence, said long-shaped square foam having its peripheral surface planed into a smooth circumferential surface:
• and

A fifth step:

• Said long-shaped square foam able to be planed into a column-shaped foam after said long-shaped square foam completely passes through said knife base, said column-shaped foam guided and sent out through said material-delivering device, thus finishing the process of shaping said column-shaped foam.
