摘要： Method for producing an aerosol dome having a dome region with an upwardly adjoining rolled rim arranged at an upper passage opening and with a downwardly adjoining flange region with an everted portion. An intermediate stage is prepared in one or more stages from a lacquer-coated blank (R), the intermediate stage having the upper passage opening, followed downwardly by a neck portion, then followed by the dome region, which is followed by an encircling straight flange. The intermediate stage is processed in a processing stage (S9) in which only the everted portion is formed.

摘要： The invention relates to a method for producing a rolled edge from a cylindrical edge portion (11) of a pipe. In the method, a starting zone (14) of the edge portion (11) is rolled by a forcibly controlled tool (30). A flanging die (21) then advances into the rolled edge portion (11) and flanges the rolled edge portion into a roll (12). The method according to the invention is characterized in that the starting zone (14) of the edge portion (11) is folded over by the tool (30), which comprises a folding die (37) and counterholder (34), at an angle (α) in the range from 75-105° from the axial direction (45) into a substantially radially peripheral flange (41). The invention further relates to elements, in particular in the forme of an aerosol dome, having such rolled edges.

摘要： An apparatus (1) for the clocked longitudinal transport of workpieces (11) between processing stations in a transfer press. The apparatus has, at least on one side, a first (2) and a second (3) longitudinally movable control element as a control group (2, 3), wherein two control elements (2, 3) are mounted to be movable relative to each other solely in the longitudinal direction, and the control elements (2, 3) are driven via a common shaft (58). The first control element is a gripper rod (2) for the longitudinal transport of workpieces (11) between the processing stations, and gripper elements (4), offset in the longitudinal direction by the distance between the processing stations, are mounted in the gripper rod (2) and can be moved solely in the transversal direction. The second control element is a thrust rod (3) which forcibly controls the transversal movement of the at least two gripper elements (4).
