The invention relates to an improvement of the invention disclosed in aer II'-OS Z '^ 20 oll of April 16, 197p.

If you use one or more the flaps are attached to a hat, with the support pad and the cockroaches on it at the ends of the the flaps are outside the labe. The honeycomb is rotated while Hit the flaps against the substrate to be hammered. the

.tis has now been found, lasts the useful life of the hammer valve structure is greatly increased if the hammer particles are unrelated on the elongated flap at an acute angle of inclination of the ha-m-aerfläcne of the support base to the length of the flap fixed from 25 ° to oü °.

sgeiUäiJ „irα aaner a iiäioiüklappen construction from one Flexible, elastic, tough, shock-absorbing, tear-resistant material with high flexural strength and dimensional stability is suggested. Liinaesxens is a xiäiikierteilchen-carrier pad mechanically on a long stretched-out, one end of the same Neighbors mesh in eix.'eni acute angles of inclination of the Haima.erfläcrxe the 'i' support bracket is attached to the strap length of 25 to 80 °. The support base consists of a tetall that is strong able to withstand bending and impact stresses and anx deformation withstands a multitude of refractory, hard, Schnlagbrucnfescer Hämnierteiicnen is metallurgically to one exposed (uncovered) surface of the l'rager pad bound.

Fig. 2 is a front view of one of those shown in Fig ^{. Jj 1} Ig. 1 flaps shown; Fig. 3 is a ± length view of that in I ¹ Ig. 2 flap shown; and Flg. 4 is a rear view of the FIG. 2 flap shown.

In the drawing, a high-intensity HamLierklappe, general denoted at 40, which are constructed in accordance with the invention is.

jj ± e Hämaierklappe 40 has an elongated flap 42, two hammer part-i'rägerunterlagen 43 and 45, which are supported in the hold on the washer 42 by guide washers 46, and

The elongated .lasche 42 'consists of a flexible, elastic, fierce, shock-absorbing, tear-resistant "... material with greater flexural fatigue strength and dimensional stability. The tab must have these properties in order to withstand the hammer blow, while the emiating particle carrier pads located thereon 43 and 45 are held, and about the particles to bring back into position for "more sewing strokes, An extremely satisfactory combination of the required Jiiigenscaften was made with a polyurethane impregnated Nylon coarse fabric found, started as "Heevecote" 7625 and from Reeves.

Nylon coarse fabric impregnated with neoprene has also proven itself Proven to be very satisfactory, these materials exhibit the necessary assets, wooei the fortitude, Tear resistance and shape resistance of the nylon coarse fabric to be delivered.
