Abstract: An attachment device (1) consisting a solid body fastening the sieve frame (2) to the sieve box (3) by attaching first to the sieve box protruding out to slide through an existing hole in the sieve frame or an independent solid (6) entering through the sieve frame then attaching to the sieve box (3). The cylindrical attachment device (6) enters through sieve frame (2) to fasten to the sieve box (3). The attachment device (1) may contain a moveable head (8) once the device is place through at least one hole on the sieve frame (2) fastening to the sieve box (3), the moveable head (8) bends snapping in place to maintain the attachment of the sieve frame (2) to the sieve box (3).

Abstract: A disposable sieve frame (10) comprising a body structure (12) constructed from one or more layers of a synthetic material, and a pre-tensioned screen (14) constructed from a synthetic or metal material and secured by a chemical adhesive or a layer of melted material or by melting the screen material to a perimeter member (16) and an interior member (18) of the body structure (12) so as to result in a substantially flat sifting surface, and a method of making the same.
