Abstract
In the area of manufacturing covers with tear-open foils, the cover blanks, or covers are always secured against an undesired take-off from the transport means during the transport and the processing. This allows a very high manufacturing cadence equally for light covers and particularly for aluminium covers.
Claims3
An apparatus (1) for manufacturing covers (20) with tear-open foils, the apparatus comprising:
- a linear transport means (3) for transporting cover parts substantially horizontally along a manufacturing path, the linear transport means including defining a longitudinal central axis and comprising a first belt on a first side of the longitudinal central axis, a second belt on a second side of the longitudinal central axis, a plurality of first receptions and a plurality of second receptions,
- wherein each of the plurality of first receptions is formed by a pair of entraining lugs arranged in succession on a first belt and a pair of entraining lugs arranged in succession on a second belt,
- wherein, for each of the plurality of first receptions, the entraining lugs of the pair arranged in succession on the first belt are separated by a first lug distance (a) and the entraining lugs of the pair arranged in succession on the second belt are separated by the first lug distance (a),
- wherein each of the plurality of second receptions is formed by a pair of entraining lugs arranged in succession on a first belt and a pair of entraining lugs arranged in succession on a second belt, and wherein none of the entraining lugs forming one of the plurality of second receptions also forms one of the plurality of first receptions,
- wherein, for each of the plurality of second receptions, the entraining lugs of the pair arranged in succession on the first belt are separated by a second lug distance (b) and the entraining lugs of the pair arranged in succession on the second belt are separated by the second lug distance (b),
- wherein the plurality of first receptions and the plurality of second receptions are arranged in alternating along the longitudinal central axis, and
- wherein the linear transport means is adapted to transport the cover parts stepwise to a plurality of processing stations along the manufacturing path with steps positioning one of the first plurality of receptions or one of the second plurality of receptions at one of the processing stations.
