A device for the dimensionally accurate application of an elastoplastic spacer strip onto a glass pane is disclosed. The device includes a compensating or tailback section between a first adjustably driven pair of rollers and a second adjustably driven pair of rollers, as well as a sensor for recognizing the position of the strip in the compensating section. The device is designed such that the spacer strip is not withdrawn from the storage drum but, instead, is unwound in a manner free from any tensile stress. The spacer strip, furthermore, is kept free from tensile and shearing stresses on the route up to being pressed onto a glass pane, despite the fact that the application speed will inevitably fluctuate several times between zero and a maximum value while edges of the glass pane are covered mechanically.

I claim: 1. An apparatus for the mechanical application of an elastoplastic spacer strip onto a glass pane, the apparatus comprising: a supporting wall for the glass pane inclined relative to the perpendicular, the supporting wall including a lower edge and an upper edge; at least one horizontal conveyor proximate the lower edge of the supporting wall; a pillar oriented within a plane parallel to the supporting wall; an application head disposed on the pillar and movable between the lower edge and the upper edge of the supporting wall, wherein the application head turns stepwise about an axis orthogonal to the plane of the supporting wall; a machine control unit operable to monitor and control the movements of the apparatus and the transport of the strip; an application head operable to apply the strip at a momentary application speed; a first strip conveyor including a first pair of rollers driven at a first rotational speed regulated by the machine control unit; a second strip conveyor including a second pair of rollers driven at a second rotational speed regulated by the machine control unit; a compensating section located between the first strip conveyor and the second strip conveyor, the compensating section defining a guide slot permitting the lateral movement of the strip therein, wherein the compensating section is configured to prevent the exertion of tensile and compressive stress on the strip in the compensating section; and a sensor operable to detect the lateral movement of the strip within the guide slot. 2. The apparatus of claim 1, wherein: the compensating section comprises a plurality of guide rollers to support the strip as it moves along a running direction; the sensor comprises a first sensor and a second sensor operable to detect the movement of the strip in a direction transverse to the running direction; and the first rotational speed of the first pair of rollers is altered when the first sensor or second sensor detects transverse movement of the strip. 3. The apparatus of claim 2 wherein: the rollers of the compensating section form an arc; and the strip is guided in an arc possessing a radius primarily dependent upon the difference between the circumferential speeds of the first and second pairs of rollers. 4. The apparatus of claim 1, wherein: the sensor further monitors the length of the strip in the compensating section; the strip length is defined by a predetermined setpoint length; and the first rotational speed is adjusted in response to the strip length falling outside of the predetermined set point length. 5. The apparatus of claim 1, wherein the compensating section comprises a plurality of guide rollers oriented in parallel, arcing relation such that the guide rollers define a guide slot permitting the passage of the strip through the compensating section. 6. An apparatus for the mechanical application of an elastoplastic spacer strip onto a glass pane, the apparatus comprising: a supporting wall for the glass pane inclined relative to the perpendicular, the supporting wall including a bottom edge and an upper edge; at least one horizontal conveyor in the zone of the bottom edge of the supporting wall; a pillar in a plane parallel to the supporting wall; an application head movable on the pillar between the bottom edge and the upper edge of the supporting wall, wherein the head is configured to turn stepwise about an axis orthogonal to the plane of the supporting wall; devices operable to supply the strip from a storage drum, as well as to press and dimensionally cut the strip; and a machine control unit configured to measure, control, and monitor the movements of the apparatus and the transport of the strip, wherein the devices for supplying the strip comprise: a first strip conveyor including a first pair of rollers driven by a drive mechanism regulated via the machine control unit, wherein the first pair of rollers is driven at a first rotational speed; a compensating section including supporting rollers for the strip; a second strip conveyor including a second pair of rollers driven by a drive mechanism regulated via the machine control unit, wherein the second pair of rollers is driven at a second rotational speed; and at least one sensor operable to monitor the length of the strip in the compensating section, wherein the first rotational speed is adjusted to maintain the length of the strip in the compensating section within an average setpoint length to prevent the exertion of tensile stress and compressive stress on the strip. 7. The apparatus of claim 6, wherein the storage drum has an unwinding drive that can be adjusted synchronously to the application speed via the machine control unit. 8. The apparatus of claim 6, wherein the compensating section between the first and second pair of rollers comprises at least one guide slot for the strip, with the long axis of the guide slot extending in a substantially orthogonal manner to the direction of the strip transport and the slot width being only slightly larger than the width of the strip. 9. The apparatus of claim 6 further comprising a swivelable lever disposed at an application point, the lever configured to support the strip close to the application point during the turning of the application head. 10. The apparatus of claim 6, wherein the at least one sensor comprises: a first sensor to monitor a maximum deviation of the strip from a stretched position; and a second sensor to monitor a maximum approximation towards the stretched position. 11. The apparatus of claim 6, wherein a rotational speed of the second pair of rollers is adjusted based exclusively on the momentary application speed. 12. The apparatus of claim 6, wherein the compensating section comprises a plurality of guide rollers configured to buffer the strip supply from the first pair of rollers. 13. The apparatus of claim 12, wherein: the strip travels in a running direction; and the guide rollers permit the strip to yield in a direction transverse to the running direction. 14. The apparatus of claim 6, wherein: the compensating section comprises a plurality of guide rollers oriented in spaced, parallel, arcing relation to form an arc having an inner side and an outer side; and the at least one sensor comprises: a first sensor situated along the inner side of the arc, a second sensor situated along the outer side of the arc. 15. The apparatus of claim 6, wherein the at least one sensor comprises a reflex light barrier.
