The press comprises a first generally-horizontal link (L1) below a second generally-horizontal link (L2). A third link (L3) extends down from the seco nd link to the first link and carried a press tool (70) with a generally downwardly facing working surface. A fourth link (L4) is arranged to be driven by a first mechanism (DS, M2) to push the second link and thus the press tool generally forwards from a horizontally retracted start position to a horizontally advanced initial pressing position, after which the first mechanism is arranged to hold the position o f the fourth link. A second mechanism (DS, C, L5) is arranged, when the position o f the fourth link is being held, to pivot the first link to drag downwards the thi rd link and thus drag the press tool generally downwards from the initial pressing position to a vertically lower final pressing position. |
