Abstract (en)
[origin: EP0822142A1] The present invention relates to a body flap folding apparatus in a packaging machine. Comb-shaped folding pieces (6, 7) are moved pivotally along arcuate tracks (T2, T1) from edge portions (A6, A7) of a folding surface (A5) of box-like contents (A). As a result, front ends (6a, 7a) of the folding pieces (6, 7) strike against body flaps (B2, B1) at the edge portions (A6, A7), whereby the base portions of the body flaps (B2, B1) are bent along the edge portions (A6, A7). Thereafter, resilient members (6c, 7c) are deformed in the direction opposite to their biasing direction by virtue of a reaction force from the folding surface (A5) , so that the folding pieces (6, 7) fold the body flaps (B2, B1) inside along the folding surface (A5) in a strained state of the flaps. Further, even if with return movement of the folding piece (6) for the inner body flap (B2) the inner body flap (B2) once folded tries to return in the direction opposite to the folding direction under the action of friction created between the folding piece (6) and the inner body flap (B2), the base end thereof strikes against a comb-shaped front end portion (2a) of a second holding face (2) to prevent return of the inner body flap.
