FIELD: processing meat, poultry, or fish.
SUBSTANCE: invention relates to animal origin products filleting. Disclosed is knife assembly (10) for filleting animal products, comprising at least one cutting head (11), which comprises at least one housing (12) having knife unit (13) and drive unit (14) adapted to rotate knife shaft (16), which has separating knife (15) and is installed with possibility of rotation inside housing (12), wherein separating knife (15) is located on knife shaft (16) at its free end (17) with provision of joint rotation, wherein knife shaft (16) is axially movable relative to housing (12) and can be disengaged from drive unit (14) for axially moving knife shaft (16) such that knife shaft (16) can rotate independently of its axial movement. Disclosed is device (62) for filleting animal products, comprising transport device (63) for holding and conveying the products to be treated in a conveying direction T along a conveying path and at least one workstation (64) along the conveying path for processing said products, wherein workstation (64) is said knife unit (10). Additionally, proposed a method for animal origin products filleting using the said device involving the following stages: supply of product to be treated to at least one workstation (64) by means of transport device (63) in direction T of conveying, cutting the product to be treated using knife unit (10) as workstation (64) by transporting said product along at least one rotary separating knife (15) of cutting head (11) of knife unit (10), wherein rotating separating knife (15) is moved in the axial direction from the ready position to the cutting position and back, or vice versa, in order to position it relative to the product to be treated, wherein for axial adjustment of separating knife (15), which is combined with its rotational movement, only knife shaft (16) carrying separating knife (15) of cutting head (11) of knife unit (10) is moved relative to housing (12).
EFFECT: invention provides creation of compact and dynamically adjustable knife unit that cuts even small products by reliable, accurate and highly efficient method, and also provides for appropriate device and method for animal origin products filleting.
