Apparatus for cutting curd, including a curd vat with drive shaft and cutting frames with a U-shaped or closed frame for longitudinal knives and transverse knives. The transverse knives are caught by their ends by recesses provided in the side frame girders. The longitudinal knives may be caught by recesses provided in the transverse knives, which are each open towards one side of the transverse knife, the transverse knives being mounted in the side frame girders such that the longitudinal knives are caught by transverse knives alternately having open sides of those recesses extending to one and the other side. The outer transverse frame girder may comprise a slightly outwardly extending knife section over a substantial portion of its length.
