This relates to a pallet for carrying and simultaneously presenting to a plurality of blow molds preforms. The pallet includes an elongated bar which has rotatably journalled therein a number of collets and the bar is provided with support and guide rollers which are engageable with opposed channel-shaped track members to guidingly support the pallet for movement along a predetermined path and into the space between one set of blow mold halves. The pallet is provided with drive means for effecting the feeding thereof together with a holding pin to permit the retention thereof in a selected position. Each collet is rotatably journalled within the bar so that it may be rotated to facilitate the even heating of the preforms. The lower end of each collet is provided with ball detent devices which are so associated with a retaining surface on each preform so as to effect a tight, but releasable, holding of the preform within the collet in alignment with the collet. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
A pallet particularly adapted for carrying preforms in a blow molding machine, said pallet comprising an elongated flat bar, first notches formed through said bar along opposite edges of said bar at longitudinally spaced portions and in the thickness direction, support rollers seated in said first notches within the width of said bar and projecting above and below said bar in the thickness direction, second notches formed in and opening from opposite edges of said bar at longitudinally spaced intervals, guide rollers lying within the general plane of said bar within said second notches and extending outwardly from opposite sides of said bar, and preform holders extending through said bar at longitudinally spaced intervals.
