Retrofitting existing let-off devices with BLDC control
Due to the increasing demands on quality, punctuality and costs, textile companies are called upon to permanently optimise their machinery and production processes.
Warp thread tension is an important process in weaving. From the full to the empty warp beam this parameter must be kept constant.
The same conditions must be created for weaving from creel, because, in both cases, warp thread tensions that are too high or too low lead to warp thread breaks, which counteracts good weaving behaviour.
Three central benefits
With electronic warp let-off devices from CREALET weavers can benefit in three ways: The balanced tension reduces the machine load, increases the efficiency and improves the fabric quality.
With the BLDC control, presented for the first time at the ITMA 2019 in Barcelona, and the corresponding load cells, existing let-off devices can be retrofitted.
When retrofitting, however, considerations must also be made with the regard to safety regulations. Special attention must be paid to warp beam handling and bearing.
For this reason, we use safety chucks for larger warp beams. These offer safety during unwinding and winding. The closing mechanism can only be opened when the machine is at a standstill and when the opening mechanism is at the top.
It is also very easy to insert the warp beams using the inclined handwheel.
