The lower slat conveyor has lateral containment blocks at the ends of its slats. At least some of the blocks are provided thereon with the inserts to be incorporated in the foamed layer, for picking and placing the inserts on the engaging elements provided in the apparatus.

Abstract: An apparatus for feeding stapling elements grouped in sets to a stapling machine which is suitable to insert the elements astride the joint of strips arranged at an angle in order to provide perimetric frames, supporting frames and the like, comprising a magazine which is composed of at least one inclined channel suitable to accommodate a plurality of aligned sets and having a downward outlet for the sets, means for individually releasing the sets from the at least one channel through the outlet, a holder which comprises at least one seat arranged below the outlet of the at least one channel, actuators for actuating the holder between a position for receiving a set from the at least one channel in the at least one seat and a position for positioning the set with respect to the stapling machine so as to align the punch of the machine with the stapling elements to be inserted.

Abstract: A device for mating strips joined at an angle for forming rectangular frames having a L-shaped element, acting as movable abutment for the strips, has a symmetrical hinged connection to a pair of linkages, pivotally connected to a free end to the supporting element fixed to the platform, and an arm protruding outside the L-shaped element along the extension of its bisecting line and undergoing elastic centering. The element and linkages are accommodated in the supporting element in two mutually aligned seats which lie transversely to the slot of the platform, and are each constituted by a bush from which a slider protrudes; the slider is pushed, until it rests against an abutment of the bush, by a cylindrical spring which acts between the slider and the screw-type cap used also to adjust the preloading of the spring.

Abstract: A mold for manufacturing plastic items, composed of a female mold half and of a male mold half which are mutually aligned along a vertical axis, the male mold half being composed of a sleeve and a plug which is guided inside the sleeve and is movable with respect thereto; the female mold half comprises a base plate, a bush which is guided on the base plate and forms, together with the base plate, a cavity for receiving a dose of plastic material to be molded, the bush being provided with an abutment which acts as a locator for the sleeve during molding, the bush being movable with respect to the base plate in contrast with elastic return means which allow the plug to enter said cavity.

Abstract: A frustoconical matrix and a punch of a complementary shape and coaxial to the former can be brought together to shape an inserted sheet of thin paper. The matrix has a cylindrical peripheral surface along which a beading member comprising a cylindrical foil is slidable in a close running fit. A shoulder extends coaxially to the punch to define a pit having a cylindrical internal wall having a diameter smaller than the outside diameter of the beading member. Heating means are controllable to heat the shoulder to a temperature such that the pit is expanded to a diameter of close running fit between its internal wall and the beading member.
