## Abstract

Dough sheet perforator comprising plurality of axially spaced and aligned star wheels rotating against individual resilient backup members as sheeted dough is passed therebetween to assure complete dough perforation resulting from extended scraping action of teeth of star wheels along associated backup members.

## Claims

### Claim 1

A dough perforator comprising a rotatable star wheel toothed member, means for guiding a sheet of dough over and into contact with said toothed member to be penetrated thereby, and a sheet metal spring backup member engageable by said toothed member to effect a lineal scraping of said toothed member thereon, whereby an aperture is formed completely through said dough sheet to prevent forming of any aperture-closing membrane thereover.

### Claim 2 (depends on 1)

A dough perforator according to claim 1, wherein said backup member comprises a spring finger mounted to position a free end thereof in the path of movement of said toothed member.

### Claim 3 (depends on 1)

In a dough perforator according to claim 1, means for guiding a perforated sheet of dough and separating the same from said toothed member.

### Claim 4

In a dough sheeter having rollers for sheeting a dough piece, and drive means for rotating said rollers; dough sheet perforator means, comprising an axially aligned and spaced set of dough sheet perforator members rotated by said drive means, means for guiding a dough sheet into contact with said perforator members, and a backup unit including sheet metal spring members individually cooperating with said perforator members to effect lineal scraping thereagainst of the latter, whereby spaced apertures are formed completely through a dough sheet to prevent forming of any aperture-closing membranes thereover.

### Claim 5 (depends on 4)

In a dough sheeter according to claim 4, means for guiding perforated sheets of dough and separating the same from said perforator members.

### Claim 6 (depends on 4)

In a dough sheeter according to claim 4, adjustable means for mounting said dough sheet perforator means axially parallel to said rollers.

### Claim 7 (depends on 6)

In a dough sheeter according to claim 6, means for adjustably mounting said backup unit relative to said perforator members.

### Claim 8 (depends on 7)

A dough sheeter according to claim 7, wherein said backup unit comprises a sheet of spring metal having a longitudinally extending base portion and a finger portion angularly disposed relative thereto defining fingers spaced from each other and individually aligned with said perforator members.
