Conversion lines from 
have been developed for producing bottom folded and sewn woven sack made from roll of tubular woven PP/HDPE fabric. bcs 850/40 model from LOHIA is a high speed machine suitable for conventional bag application and is designed for cross cutting the tubular fabric, bottom folding, sewing and stacking. This new generation machine with servo and PLC controls is designed for fabric width upto 850 mm and with speeds upto 40 bags/min. depending upon material, width of the fabric, number of folds, stitches etc. This bag making machine is most appropriate for working with un-laminated fabric but can also be converted to use laminated fabric on the specific demand of the customer. Following advantages make these bags making machines the best choice.
- State of the art automated functions result in consistent quality of end product i.e. cut & sewn bags.
- Reduced space requirement for converting the roll of fabric to the finished bag.
- Reduced manpower requirement for producing the same quantity of bags.
Unwinding Unit
bcs 850/40 automatic cutting and sewing machine consists of an unwinding unit where roll of circular woven fabric can be easily mounted without any requirement of external lifting device. Edge position control unit (EPC) supplied with the machine takes care of minor variations in fabric rolls and maintains edge of the fabric in line with the transfer unit.
Accumulator Unit
The accumulator unit is provided to accommodate and keep reserve of any extra length of fabric opened during continuous unwinding and is also helpful in maintaining uniform tension of fabric. Print mark sensor is supplied as standard with the machine to cut the fabric as per marking on pre-printed fabric roll. 
Cutting Unit
Machine is equipped with a hot cutting unit suitable for un-laminated fabric in conjunction with mouth opening device which helps in easier opening of leading edge of the cut length. Servo motor used is helpful in cutting the fabric of pre-set length with minimum cut length variation. 
Bag Stacking & Conveyor Unit
The finished bags are discharged onto a delivery conveyor after counting and stacking the pre-set number of bags.
Bottom Folding & Sewing Unit
These cut lengths are then transferred to the bottom folding and sewing unit with the help of transfer conveyor. With the help of sensors provided, the sewing machine can be automatically stopped for the duration when no cut lengths are received from cutting unit in case of any problem or exhaustion of fabric roll etc. Variable frequency drive system is provided to synchronize the cutting unit, conveyor and sewing unit. The thread cutter unit is operated through an electronic sensor.
