Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
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
Dependent Claim
69 words
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 3
Dependent Claim
31 words
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 4
Dependent Claim
24 words
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 5
Dependent Claim
92 words
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 6
Dependent Claim
92 words
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 7
Dependent Claim
23 words
In a dough sheeter according to claim 4, means for guiding perforated sheets of dough and separating the same from said perforator members.
Claim 8
Dependent Claim
22 words
In a dough sheeter according to claim 4, adjustable means for mounting said dough sheet perforator means axially parallel to said rollers.
Claim 9
Dependent Claim
20 words
In a dough sheeter according to claim 6, means for adjustably mounting said backup unit relative to said perforator members.
Claim 10
Dependent Claim
44 words
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.
