Abstract: The projecting end of a wrapper tube about a commodity, e.g. bakery products, so as to extend beyond the front end face of the commodity by a distance exceeding the radius of the tubed wrapper, is closed by firstly simultaneously folding in indentical sections 151 nequally distributed along the periphery of the front end face of the commodity in a direction toward the front end face of the commodity to inclined positions with the fold lines 152 of the folded-in sections forming generatrices of a first conical frustum. Webs 153 thus project outwardly between the fold lines and the outer marginal edges 154 of such webs form generatrices of a more pointed second conical frustum so that the folded projecting wrapper end is converted into a conical frustum with a corrugated surface. The folded-in sections are thereupon pressed against the front end face of the commodity, one after the other, with attendant formation of triangular segments which lie against the commodity and between which webs, which at such time also exhibit a triangular shape, extend outwardly. The triangular webs are thereupon folded in the circumferential direction such that they overlap each other adjacent to the front end face of the commodity. Means for carrying out such steps are also provided, said means comprising a ring of triangular folding plates 124. <IMAGE>

Title: Bearing support structure
Inventor: WILKINSON WILFRED HENRY
IPC: F16C19/52
Filed: 1981-10-30
Abstract: Differential expansion between the bearing support structure (27, 28, 29) and a turbine or compressor casing 23 is accommodated during warm-up of the engine by arranging that spigots 40 on spokes 29 are slideable in holes 41 in housings 35, the bearing being held concentric with casing 23 by means of spring washers 49 acting between the housing 35 and retaining nut/washer 46/47 on spigot 40. When normal running temperature is reached, clearance 51 becomes zero and faces 39 and 45 abut, providing a limit of accommodation to the differential expansion and ensuring sufficient radial rigidity of the support structure to transmit large out-of-balance forces to casing 23 in the event of the compressor or turbine rotor accidently becoming unbalanced, as by loss of a rotor blade. The spring washers may be replaced by coil springs or elastomeric bushes. The expansion accommodating means may be at the radially inner ends of spaces 29, and the spigots may be provided on the casing 23 or ring 28 instead of on the spokes. In a further alternative the expansion accommodating means is at the middle of each spoke. <IMAGE>
