摘要
A process and device are disclosed for uniformly applying fluid sealing material (compound;C,R) in the body or cover hook (81;81i,81n,81r) of a lid (D) in order to prepare a tight double seam closure. A plurality of needles (30a,30b,30c,...;30x) or a continuous projecting ring (37,38) enter with their front ends (35a,35b,35c,...;35x,38) through one or several bottom openings (40;40x) in a continuous application channel (48) with two delimiting edges (45b,46b). The axial position of the needles (30x) or projecting ring (37,38) in the channel (48) may be adjusted from behind (31a,32a,...;31x,32x) without their ends (35a,...,35x,38) at the channel side having to absorb axial adjusting forces from the body or cover hook (81n). The compound (fluid sealing material) may thus be more precisely, more uniformly and more gently applied on the body or cover hook, and damages to the metallic application point are avoided, in particular in the case of metal sheets of less than 0.24 mm thickness. Although the compound is applied more gently, it is precisely dosed and positioned, so that the resulting sealing ring (R) has exactly the width, thickness and position required in the cover or body hook to ensure the tightness of the double seam closure formed therefrom. The amount of sealing material (C) used can also be reduced.
