The table assembly includes a rigid forward table extending along and parallel to the lengthwise path of movement of the press, and an elongated rearward table positioned in rearwardly spaced relation to the front table. A flexible elongated strip of dielectric material is positioned tautly between the forward edge of the rear table and the rear edge of the forward table and the lapped fabrics to be heat sealed are positioned over the complaint membrane during the sealing operation. The rear table is supported by a plurality of straps positioned beneath the table and secured at their opposite ends to tensioning devices including ratchet means for selectively tensioning each of the belts.
