Abstract

An apparatus for producing tubular waffle shapes from a strip of waffle material wound helically on a mandrel in edgewise overlapping relationship, and contacted by steam before overlapping to adhesively bind the adjacent convolutions. The overlapping edges are pressed together by a guide roller to assure good adhesion and the tubular waffle shape is completely filled with a creamy substance and is cut into predetermined lengths before hardening. The guide roller is mounted to feed the strip obliquely on the winding mandrel, and also exerts pressure against the overlapping edges of adjacent convolutions and advances the wound body on the mandrel.

Claims

1. A device for the production of filled continuously wound shell-type waffle bodies comprising:

a. a rotating winding mandrel, said mandrel having a relatively large substantially constant diameter longitudinal bore therethrough, said bore being of sufficient size to flow a cream-like substance therethrough, b. guide roller means positioned over the longitudinal axis of said mandrel and adjacent thereto, c. means for feeding warm, plastic deformable dough oblique to and over said mandrel in an overlapping manner, d. pressure feed means for supplying the cream-like substance through said longitudinal bore to the inside of the wound body, e. cutting means for separation of the continuously wound body into discrete lengths, said cutting means including a pair of scissor-like shearing members.

2. A device as defined in claim 1 including means positioned below said guide roller means for spraying a source of steam into the wedge-shaped gap at the point of winding between the dough being fed to the mandrel and the last winding of the body.

3. A device as defined in claim 1 wherein said guide roller means includes a concave outer surface for facilitating the application of pressure against said mandrel.

4. A device as defined in claim 1 wherein the longitudinal axis of said guide roller means is oblique to the axis of said longitudinal bore.

5. A device as defined in claim 1 wherein the longitudinal axis of said guide roller means is parallel to the axis of said longitudinal bore.

6. A device as defined in claim 5 wherein the circumference of said guide roller means is threaded to facilitate the advancing of the body along said mandrel.

7. A device for the production of filled continuously wound shell-type waffle bodies comprising:

a. a rotating winding mandrel, said mandrel having a relatively large substantially constant diameter longitudinal bore therethrough, said bore being of sufficient size to flow a cream-like substance therethrough, b. guide roller means having a longitudinal axis positioned parallel to the longitudinal axis of said mandrel and adjacent thereto, said guide roller means being threaded to facilitate the advancing of the body along said mandrel, c. means for feeding warm, plastic deformable dough oblique to and over said mandrel in an overlapping manner, d. pressure feed means for supplying the cream-like substance through said longitudinal bore to the inside of the wound body, e. cutting means for separation of the continuously wound body into discrete lengths.
