ABSTRACT:
The known type of front and rear flap folding apparatus in a wraparound caser in the prior art is improved in that the folding apparatus comprises front flap folding means in which when an article is fed from a dead plate onto a flat blank sheet that is being transported as placed on a sheet receiver of a case transporting conveyor, front flap folding guide members mounted to the case transporting conveyor are erected by a roller follower which rolls along a cam rail to fold the front flap of the sheet, rear flap folding means in which after the article has been fed onto the sheet, rear flap folding guide members mounted to the case transporting conveyor are erected by a roller follower which rolls along a cam rail to fold the rear flap of the sheet, and combined guide and press members which press the article and the sheet while guiding the article upon the above-mentioned folding operations to prevent them from rising up from the sheet receiver.
