Description: |
| Original application 07 February, now Patent No. (2,618,207}, dated 18 Nov., 1952. Divided and this application 09 January, 1952.
Claim:
In the form of machine disclosed in the copending application, the plastic sheet is fed from a continuous roll and blanks are severed from the roll. These blanks are fed progressively through the machine for a series of operations thereon, the ultimate product being a four-sided box, the sides of which are firmly united together. In passing through the machine of this invention, the blank is subjected to a trimming operation and successive wall forming operations at which the material is crimped or formed under heat and pressure to define a bottom and four sides. The sides are bent into substantially perpendicular positions with respect to the bottom, after which they are brought together and adhesively joined or merged at the corners. The present application relates to the mechanism for feeding the sheet material from the roll, severing it into measured lengths and advancing the severed sheets from the feeding mechanism into the box forming machine. |
