Method and apparatus for making compact packages for spreadable products involving flights mounted on a conveyor chain having tiny cam operated pivoting clamps which open to precut cards fed in by a card feeder. The pivoting clamps on the flights are opened by cam pressure and pick the cards on the fly as they travel. After passing the end of the cam they close down on the card. The cards are then, after passing over rails with spring resistance members, transported through a unique rotary scoring and bending assembly, which simultaneously scores and bends up longitudinal side flanges to create a channel shaped member from the flat paperboard card.

1. A machine for producing packages of spreadable products comprising:a single roller chain having at least one flight assembly for scooping up, clamping, and driving a card member ahead of it mounted thereon comprising a flight body, a centrally pivoted clamp member pivoting in a see-saw manner on a first shaft held in place at each of its ends by said flight body, said at least one flight assembly including a flat spring for driving, in a see-saw manner and holding, said centrally pivoted clamp member in a given direction to a first and clamping position and a cam follower roller mounted on a second shaft mounted in said centrally pivoted clamp member to drive, by means of a fixed cam, said centrally pivoted clamp member in a reverse see-saw manner opposing the force of said spring to rapidly pivot said clamp member to a second and open position to scoop up the card by said clamp member.
