An improved method and an associated improved device for operating a linear-motor-driven simultaneous stretching installation is distinguished inter alia by the following features: during normal operation, the linear-motor-driven transporting units (T) in the simultaneous stretching zone (R) are subjected to an acceleration phase with a normal-operation acceleration profile involving a growing increase in the distance (MDx-y) from a following transporting unit (T) driven by the linear motor drive; when the web of material (F) is moved into the stretching zone (R), at least two leading tenters (6), following one another and driven by the linear motor, are accelerated in the stretching zone (R) in such a way that differs from the normal-operation acceleration profile that the distance (Mda.b) formed between the at least two tenters (6) following one another and driven by the linear motor is less than 80% or less than 75% of the distance (MDx-y) that is brought about during normal operation. |
