ABSTRACT:
Articles (18) are transferred from a first position, such as a feed track (37) on which they are located closely spaced, to a second position such as a heat seal apparatus. At the heat seal apparatus the spacing of the articles is to coincide with the spacing of frame members (32) to which the articles are to be joined. The change in the spacing occurs during the transfer of the articles from the first to the second positions by means of a transfer mechanism (41). A plurality of pickup members (43) are slideably mounted to an arm (44) of the mechanism (41). The pickup members (42) which are resiliently urged apart with respect to each other are forced together at one end of the travel of the arm (44) to assume the close spacing established by the width of the pickup members. At the other end of the travel of the arm (44) the resilient urging force drives the pickup members (43) against predetermined stop positions.
