摘要:
The invention relates to an indexing-motion packaging apparatus (34) for an indexing-motion packaging machine. The apparatus comprises a forming station (10) comprising first and second forming die members (36, 38) and a closing station (14) comprising first and second closing die members (42, 44). A lift (50) is provided that operatively couples at least three members (36, 42, 44) of the first and second forming die members (36, 38) and first and second closing die members (42, 44) together such that operation of the lift (50) counterbalances and moves the three members (36, 42, 44) together between the respective open and closed positions.

The invention relates to a system for supplying a web of packaging material to a packaging machine, the system comprising: a motor (14) rotating a roll (16) of a web of packaging material (12), a conveyor conveying the web (12) from upstream to downstream. The system is characterized in that it further comprises the system further comprises a dancer (36) located downstream of the roll (16) and upstream of the conveyor, the dancer (36) being movable between first and second positions based upon a change in tension of the web (12), and a control circuit (154) controlling the motor (14) and being in communication with at least one sensor (56) sensing the position of the dancer (36), wherein the control circuit (54) controls the motor (14) to rotate the roll (16) to thereby cause the dancer (36) to move from the first position to the second position, wherein the control circuit (54) calculates a starting speed of the motor (14) based upon the movement of the dancer (36) from the first position to the second position, and further wherein the control circuit (54) controls the motor (14) at the calculated starting speed to begin supplying the web (12) to the conveyor.
摘要:
The invention relates to a packaging apparatus comprising a web transport conveyor (4) transporting a web (6) of flexible packaging material from upstream to downstream locations through a series of stations including a forming station (10) for forming at least one pocket in a first web (6) of packaging material and a loading station (12) for placing food product in the pocket, the food product having packaging material comprising a foldable flap (84) extending generally outwardly away from the conveyor (4), wherein the packaging apparatus comprises a closing station (14) located downstream of the loading station (12) for closing the pocket with a second web (16) of packaging material. In this packaging apparatus the second web (16) of packaging material is oriented in the closing station (14) so as to engage with the first web (16) of packaging material and also fold the foldable flap (84) downwardly with respect to the conveyor (4) as the conveyor (4) moves from upstream to downstream.
