Abstract: Sealing tools for use in a thermal sealing machine each have a plurality of ridges oriented to engage together on opposite sides of a plurality of thermally bondable foils with the tools at substantially different operating temperatures when engaged with the foils during a sealing operation. These tools are made by first manufacturing one of the tools to a predetermined ridge-to-ridge spacing and then ascertaining the ridge-to-ridge spacing of the one tool at the respective operating temperature. Then a difference between a ridge-to-ridge spacing of the other of the tools is calculated at a predetermined manufacturing temperature and the respective operating temperature. Finally the other tool is manufactured at the manufacturing temperature with a ridge-to-ridge spacing equal to the ridge-to-ridge spacing at the respective operating temperature minus the calculated difference.

Abstract: An apparatus for loading small objects into respective blisters of a foil web has a plurality of substantially identical fill plates each having an array of receptacles corresponding to the blisters of an area of the foil. A conveyor moves the fill plates one after another in a transport direction at an upper level from a fill station remote from the web to a transfer station close to the web, then lowers them to a lower level, then returns them in an opposite return direction from the transfer station to the fill station, and finally raises them in the transfer station to the upper level. At the fill station the receptacles of the plates are filled with the small objects. At the transfer station the small objects are taken out of the receptacles of the plates and put into the blisters of the web.

Abstract: An apparatus for sorting small cylindrical objects has a trough having a longitudinally extending groove along which the objects can slide. The groove is of generally rectangular upwardly open shape and has a pair of upright and horizontally spaced side walls and an upwardly directed floor bridging lower edges of the side walls. The floor is formed offset from the side walls with a vertically throughgoing slot of a width substantially smaller than a predetermined minimum object width so that if any of the objects is of a diameter smaller than the minimum object width it will fall through the slot as it slides along the floor. One of the side walls is formed at the slot with an inwardly directed braking formation engageable with the objects as they slide past the slot to rotate same about vertical axes.
