Tool  sizes  are  340  mm  in  width  and  570  in  length,  number  of  trays  per  tool  can  be  maximum  4 
according to the tray dimension in travelling direction. Sealing tool driving system and sealing force 
generator consist in a fully electro-mechanical system. 

 
 

General description. 

 

Tray in feed.

 

 

 
 A  belt  is  receiving  the  trays  from  a  previous 
conveyor.  Trays  have  to  arrive  aligned  and  at  a 
suitable distance. A smart belt will pace and group 
the  trays,  independently  of  the  previous  pitch,  to 
prepare  them  to  be  transferred  to  the  sealing 
station. These two belts can handle random feeding 
speed and allow the machine to remain in stand by, 
which  is  important,  both  for  fully  automated 
solutions  and  for  manual  operations.  Detection  of 
the  tray  is  provided  by  a  single  photo  eye 
positioned above the travelling plane.
