Abstract (en)
[origin: EP0629550A2] In a film packaging machine wherein a pair of sealing bars (26) are caused to move linearly with a film (F) so as to increase the sealing cycle time, a pair of control belts (30) are mounted so as to reciprocate in unison with said sealing bars. The control belts (30), which are oriented vertically at opposite edges of a central product conveyor (24) and adapted to grip a product being wrapped, are rotated from a drive apparatus mounted to the machine body at a speed which equals the linear speed of reciprocation. Thus, the control belts (30) do not rotate when the reciprocating motion is in the same direction as the direction in which the film and product move, and rotate at double the linear speed of reciprocation when the reciprocating motion is in the opposite direction. <IMAGE>
