Abstract: To provide a lay-up apparatus capable of precision positioning and laying of thin strips of copper foil or insulation tape on a flat plane even when there are variations in the cut lengths of the strips. A lay-up apparatus lays first and second strips of tape 101, 102 on top of two electrodes 5, 6 deposited on a photovoltaic devices panel 1. The strips of tape are unwound by first and second grippers 112, 122 and cut to predetermined lengths by first and second cutters 113, 123. The cut strips of tape are laid one on top of the other and transported by rotatable moving means 130. The moving means 130 rotates in opposite directions when laying the strips of tape it holds from the electrode 5 toward the electrode 6 and when laying the strips of tape from the electrode 6 toward the electrode 5, while using one end of the strips of tape as a reference and keeping constant the relative positions of the reference end of the strips of tape and that electrode which is nearest the reference end.

Abstract: A punch and die device for working such as punching of a pipe material is disclosed, of which internal die means can easily be inserted into a pipe material even if an open end of the pipe material to be worked has burrs inward extending therefrom, and in which it is easily detected whether the internal die means is pushed toward a lateral side or lateral sides of the pipe material and thereby firmly held. The punch and die device for working a pipe material comprises: external punch means located outside a pipe material P, and internal die means K inserted in the pipe material for cooperation with a punch 30 of the external punch means to work the pipe material P; the internal die means K being divided into two parts in a direction orthogonal to that of reciprocating motion of the punch 30 of the external punch means, one 1 of the parts having working function and the other 2 having no working function, the non-working part 2 being forward and backward movable in the opening direction, i. e.
