In some examples, the first folding mechanism 51 may be disposed to the side of the first conveying portion 31. In some examples, the first folding mechanism 51 may include a first side plate 511 and a second side plate 512 (see fig. 5) which are oppositely disposed at both sides of the first conveying part 31 and configured to be movable up and down along a vertical plane.

In some examples, the upper surfaces of the first side plate 511 and the second side plate 512 may be lower than the first conveying plane S of the first conveying portion 31 before the wrapping paper 2 is folded by the first folding mechanism 51₃₁Or with the first conveying surface S of the first conveying section 31₃₁Substantially coplanar (see fig. 5A). Thus, when the block-shaped edible oil or fat 1 passes through the first folding mechanism 51, the first folding portion P of the wrapping paper 2₁And a second fold P₂Can be positioned over the first side panel 511 and the second side panel 512, respectively.

In some examples, when the first folding mechanism 51 folds the wrapper 2, the first side plate 511 and the second side plate 512 may be moved upwardly along a vertical plane to respectively cause the first fold P of the wrapper 2₁And a second fold P₂Is erected so that the first folded part P₁And a second fold P₂Respectively attached to the first block-shaped edible oil 1Side S₁And a second side surface S₂(see FIG. 5B).

In some examples, the first folding mechanism 51 may further include a first rotating shaft 513 and a second rotating shaft 514 (see fig. 5). In some examples, the axial direction of the first rotating shaft 513 and the axial direction of the second rotating shaft 514 may be in a horizontal direction and orthogonal to the conveying direction D.

In some examples, an upstream end of the first side plate 511 may be connected to a first rotating shaft 513, and an upstream end of the second side plate 512 may be connected to a second rotating shaft 514 (see fig. 5).
