Abstract: The invention relates to a method and apparatus for folding the projecting end of a covering or decorative layer over the edge of a supporting part, where at least the edge area of the supporting part is made of thermoplastic material and where at least one heatable punching element is provided, which can be applied to the folded-over end of the covering or decorative layer. The invention proposes that the projecting end of the covering or decorative layer be folded by a folding slide, which preferably is guided in a mold holding the supporting part, and which has openings or recesses for the passage of the at least one heatable punching element, which presses the covering or decorative layer at least point-wise into the edge area of the supporting part softened by the punching element.

Abstract: A crop harvesting machine is provided having a crop feeder device that is movable through various heights via manipulation of first hydraulic cylinders. A crop gathering attachment is mounted onto a front side of the crop feeder device. A crop gathering attachment is provided having fixed height sensors that measure a distance of the attachment above the ground. A second hydraulic cylinder is provided between the crop feeder device and the crop gathering attachment to control the angle of tilt of the crop gathering attachment relative to the crop feeder device. The angle of tilt is measured by a tilt sensor. A controller is connected to the sensors and provides output to the cylinders to control the machine height and angle of tilt.

Abstract: The invention relates to a device for adapting attachments on harvesting machines to the ground surface, in particular for combine harvesters and forage harvesters. The aim of the invention is to produce a rapid adaptation to the ground surface, even at high speeds, that is extremely accurate and also cost-effective. To achieve this, a feed device (1), whose height can be adjusted by a hydraulic cylinder (5). has a shaft (7) which is aligned transversally to the direction of travel, the attachment (15) being mounted so that it can be rotated through a defined pivoting angle (9) about said shaft. The pivoting angle (9) can be modified by means of a hydraulic working cylinder (10) which connects the feed device (1) and the attachment (15), whereby the pivoting angle (9) is continuously monitored by a sensor (11). An additional sensor (18) continually measures the distance (17) of the attachment (15) to the ground surface.
