Abstract (en)

The invention is related to a blank supply apparatus (8) adapted to supply blank (10) used to form a box (14) of a package (1) to a packaging machine (12), the supply apparatus (8) comprising:a transfer path (26) adapted to transfer the blank (10) piece by piece along a transfer surface (40) by extending from a supply source (4) of the blank (10) to the packaging machine (12);a pair of rollers (30) rotatably placed on opposite sides of the transfer surface (40) and provided with a pressing region (46) on an outer circumferential surface (42c, 44c) to feed the blank (10) while pressing a strip region (24) of the blank (10) corresponding to a square edge (16) of the box (14); anda preliminary folding station (38) placed at a preliminary folding position established downstream of the pair of rollers (30) and adapted to preliminarily fold the strip region (24) of the blank (10) and give a preliminary folding angle to the strip region (24) when the blank (10) is placed at the preliminary folding position, whereinthe preliminary folding station (38) includes:a preliminary folding guide (60) placed on the transfer path (26) and provided with a lateral edge (68) extending along the transfer path (26), where when the blank (10) is placed at the preliminary folding position the blank (10) is superimposed under the preliminary folding guide (60) and a flap section (22) of the blank (10) protrudes from the lateral edge (68), the flap section (22) being provided with the strip region (24); anda folding element (64A, 64B) placed in a neighborhood of the lateral edge (68) of the preliminary folding guide (60) and provided with an axis extending along the lateral edge (68), whereinthe folding element (64A, 64B) folds the flap section (22) by pressing the strip region (24) along the lateral edge (68) and thereby establishes the preliminary folding angle of the flap section (22) with respect to the blank (10),the flap section (22) includes an inside flap (22a) located inside the box (14) during forming of the box (14) and an outside flap (22b) located outside the box (14) during the forming of the box (14),the folding element (64A, 64B) includes a first folding member (67a) adapted to fold the inside flap (22a) and a second folding member (67b) adapted to fold the outside flap (22b), andthe first and second folding members (67a, 67b) give different preliminary folding angles to the inside and outside flaps (22a, 22b).
