Performance
P76, B76 and C76 machines have a sewing speed of 24ft (7.5m) per minute to close up to 10 sacks per minute or a sewing speed on 35ft (11m) per minute to close up to 15 sacks per minute.

Installation
To minimise manpower requirements the machine should be positioned so that the input end on the conveyor received the sacks directly from the filling spout.

Note
As viewed from the operator’s side the sacks pass through the sewing head from right to left.

Range
These machines are available in three standard speeds, with manual or automatic sewing head control and for applying a wide variety of plain or sewn through tape closures.

Operation
In all but the simplest machines, it is necessary to enter the sack into the sewing head, which automatically starts, sews, cuts the thread or tape and stops again, ready for the next sack.

Specification
Construction
A fabricated head bracket carried the sewing head and motor, linked by vee belt drive. The supporting column has enclosed screw-operated height adjustment mechanism on all machines. The chain and slat conveyor has folded section frames and cross members, adjustable backrest and combined motor/gear drive unit, directly coupled to the output shaft. The electrical controls for the sewing head and conveyor motors are housed in a dust-tight enclosure behind the head bracket, with operator’s push button on the front of the machine.
