Abstract
A method of positioning a continuous strip of tops over a continuous set of receptacles prior to sealing, wherein the following steps are performed repeatedly; the set of receptacles is advanced past sealing means through a distance equal to one longitudinal pitch of the receptacles or a multiple thereof; simultaneously, the strip of tops is released over a length equal to one longitudinal pitch of the tops or a multiple of said pitch, with said strip being driven by the set of receptacles, and with the longitudinal pitch of the tops being slightly greater than the longitudinal pitch of the receptacles; and applying deformation to a central zone of each top level with the sealing means so as to shift the edges between the not-yet sealed tops so that they overlie the corresponding edges between receptacles.
