Abstract
An apparatus (10) is disclosed including an abutment (282) in the form of an elongated rod positioned in front of the sealing intermittent position which rearwardly deflects the portions of bags (12) extending out of fixtures (32) moving in an operation direction. The bags (12) then slap forwardly against a stop (284) as the fixtures (32) reach the sealing intermittent position, with the stop (284) being in the form of a plate carried by the sealing jaw (146) of the sealing position. Arms (136) are pivoted between a transport position spaced from the fixtures (32) and a compression position to engage a rod (138) with the bags (12) above an expansion prevention bar (49) of the fixtures 32 to deflect the product located in the bags (12) into a more planar condition.
