A process is provided for making bulk textured material sheeting. As a continuous supply of flat material sheeting is fed, the sheeting is repeatedly impacted with toothed knives, each knife creating a row of raised and generally pointed structures on the sheeting to texture the sheeting.

A system and method of increasing a dwell time in a foil stamping press is provided. The dwell time is readily adjusted on the fly by the user for a given operating rate. A timer is used to adjust the press to stop on top dead center with changes in images per hour. An air clutch and an original equipment air brake are used in tandem to provide the desired dwell time. A pair of timers governs a pneumatic switch for control of the air clutch and the air brake. The present system and method increase die image area capacity as compared to conventional foil stamping presses. The increased dwell time press yields a flawless foil stamped image for an impression pressure less than that required in a conventional machine for a given die, mounted at a given height upon a stationary platen, and at a given temperature.

A spacer structure for a sandwich construction, formed from a material web which is provided with a plurality of cuts and which has a material web plane as a first plane, wherein, by forming the material web, at least one support platform is formed in portions which is spaced at a distance from the first plane and is arranged in a second plane. Spacing elements run along a direction of extent (E) from the first plane into the second plane in the transition zone from the first plane into the second plane and thus the spacing elements space the first plane apart from the support platform, the spacing elements having a twist about the direction of extent thereof along the direction of extent thereof (E), the twist being formed by the shaping of the material web being performed as bending.

Disclosed herein are methods for hydroforming a handpan shell. Hydroforming a handpan shell using a mold complementary to the intended shape of the handpan shell can improve the quality and performance of the handpan while reducing the time and cost needed to form features into the handpan that allow musical tones to be produced.

A method and a press for introducing a deformation pattern into a sheet uses at least one tool unit for producing an electrolyser plate or fuel cell plate, wherein the deformation pattern in at least one sub-area has a plurality of identical pattern units lying beside one another with a pattern spacing in at least one pattern direction, and the press for forming only the sub-area comprises a tool unit, in which an upper and a lower forming die are arranged, with the interacting deformation structures of which at least one pattern unit of a sub-area is formed in a single stroke of the tool unit in the sheet guided between the forming dies, and with each stroke of a predetermined total number, the pattern introduced into the sheet is supplemented by at least one introduced pattern unit.
