4.9 Setting the tape brake
Information
If the reinforcement tape is not sewn straight relative to the seam,
the tape feeder may be too loose and/or the reinforcement tape
tension may be too low.
Ruffling is increased if the tape tension is too high and/or the tape
brake is set too tight.
The reinforcement tape tension can be set by adjusting the tape
tensioner (

p. 44 ). The tape brake regulates the tape feeder.
Depending on its equipment, the machine may be equipped with
a lower or an upper tape feeder for the reinforcement tape
(

p. 30 ).
To ensure that the reinforcement tape is fed in a way that achieves
straight seam support and the desired ruffling value, the tape brake
must be set accordingly.
The principle that is used to brake the tape feeder is identical for
the upper and the lower feeder.
