Abstract
Abstract An apparatus for shaping semolina dough ribbons into pasta products useful for lasagna. The apparatus shapes and dough ribbons to give opposite marginal edges which are undulated to provide ruffles. The apparatus comprises a frame supporting a pair of vertically spaced, transverse shafts upon which are mounted matched crimp rolls. Motor and gear means are provided to counter rotate the shafts. The crimp rolls are formed with opposite marginal, fluted edges for shaping the dough.

Claim 1
Independent Claim
218 words
An apparatus for shaping dough ribbons into lasagna strands having opposite marginal edges undulated to provide ruffles, comprising: A. a support structure; B. a first horizontally aligned shaft rotatably mounted on said support structure; C. a second horizontally aligned shaft vertically oriented relative to said first shaft and parallel thereto, said second shaft rotatably mounted on said support structure; D. means for rotating said first shaft about its longitudinal axis; E. means for counter rotating said second shaft about its longitudinal axis in response to rotational movement of said first shaft; F. a pair of matching crimp rolls, said crimp rolls each having a pair of opposite marginal peripheral edges undulated to form fluting wherein the fluting extends equidistantly within and beyond the roll radius and wherein the crimp rolls are mounted on each shaft such that the fluting of one of the rolls is both in rotational and in lateral alignment with the fluting of the other roll; G. means for fixedly connecting a first crimp roll to the first shaft so that it is caused to rotate about the shaft axis as the shaft rotates; H. means for operatively connecting a second crimp roll to the second shaft so that said second crimp roll is caused to rotate about the shaft axis as the shaft rotates.
Claim 2
Independent Claim
218 words
An apparatus for shaping dough ribbons into lasagna strands having opposite marginal edges undulated to provide ruffles, comprising: A. a support structure; B. a first horizontally aligned shaft rotatably mounted on said support structure; C. a second horizontally aligned shaft vertically oriented relative to said first shaft and parallel thereto, said second shaft rotatably mounted on said support structure; D. means for rotating said first shaft about its longitudinal axis; E. means for counter rotating said second shaft about its longitudinal axis in response to rotational movement of said first shaft; F. a pair of matching crimp rolls, said crimp rolls each having a pair of opposite marginal peripheral edges undulated to form fluting wherein the fluting extends equidistantly within and beyond the roll radius and wherein the crimp rolls are mounted on each shaft such that the fluting of one of the rolls is both in rotational and in lateral alignment with the fluting of the other roll; G. means for fixedly connecting a first crimp roll to the first shaft so that it is caused to rotate about the shaft axis as the shaft rotates; H. means for operatively connecting a second crimp roll to the second shaft so that said second crimp roll is caused to rotate about the shaft axis as the shaft rotates.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1 wherein the means for rotating said shafts includes: a first gear fixedly connected to the first shaft; and a second gear mounted on said second shaft so that it meshes with said first gear, said second shaft being pivotably adjustable relative to said second gear.
Claim 4
Dependent Claim
48 words
The apparatus of claim 2 including a pivotal adjustment means for rotating said second shaft and said second crimp roll relative to said first shaft and said first crimp roll whereby the angular orientation of said second crimp roll can be adjusted relative to said first crimp roll.
Claim 5
Dependent Claim
47 words
The apparatus of claim 3 wherein said adjustment means includes a hub, means for fixedly attaching said hub to the second shaft, and means for operatively connecting said hub to the second gear whereby said second shaft is caused to counter rotate relative to said first shaft.
Claim 6
Dependent Claim
91 words
The apparatus of claim 4 wherein the means for operatively connecting said hub to the second gear includes a tab projecting perpendicularly to the plane of the second gear and fixedly connected thereto, and wherein the hub is formed with a notch through which the tab projects, said notch forming a pair of shoulders, each shoulder having a threaded, screw-receiving bore running parallel to the plane of the hub; and a pair of screws screwed into said bores until the screw tips tighten to engage the opposite sides of the tab.
Claim 7
Dependent Claim
10 words
The apparatus of claim 5 wherein the notch is rectangular.
Claim 8
Dependent Claim
36 words
The apparatus of claim 1 wherein the fluting on each crimp roll is formed such that the peaks of each tooth on one end margin align with the peaks of a tooth on the opposed margin.
Claim 9
Dependent Claim
105 words
The apparatus of claim 1 additionally comprising: a second pair of matching crimp rolls comprising a third roll and a fourth roll mounted vertically, one on each shaft; a first means for laterally spacing the second crimp roll pair with respect to the first pair of rolls; a means for fixedly connecting the third crimp roll to the first shaft so that it is caused to rotate about the first shaft axis as the shaft rotates; and a means for operatively connecting the fourth crimp roll to the second shaft so that said fourth crimp roll can be rotatably aligned with the third crimp roll.
Claim 10
Dependent Claim
78 words
The apparatus of claim 8 wherein the first means for laterally spacing the second crimp roll pair comprises a spacer plate pair, wherein one member of the spacer plate pair is mounted on the first shaft and the second member is mounted vertically above the first member on the second shaft, wherein each member of the spacer plate pair is of equal thickness and wherein the spacer plate members are mounted on the shafts between the crimp rolls.
Claim 11
Dependent Claim
41 words
The apparatus of claim 9 wherein the spacer plate pair member mounted on the first shaft has a diameter sufficiently large so as to extend above the fluting of the crimp rolls mounted on the second shaft thereby forming a guide.
Claim 12
Dependent Claim
77 words
The apparatus of claim 10 additionally comprising a second spacer plate pair wherein a first one member of the second spacer plate pair is mounted on the first shaft and the second member of the second spacer plate pair is mounted vertically above said first member and wherein each member is mounted adjacent to the second crimp roll pair member's side opposite the crimp roll pair member's side on which the first spacer plate pair is mounted.
Claim 13
Dependent Claim
39 words
The apparatus of claim 11 wherein the first shaft has a portion relatively larger in diameter forming a shoulder and wherein the first member of the second spacer plate pair is mounted on the first shaft abutting the shoulder.
Claim 14
Dependent Claim
