摘要： For the purpose of carrying out the butt-end joining of two lengths (35, 36) of a rubberized fabric, in particular, reinforced with cords disposed parallelly at the edge to be jointed, there is foreseen a stitching device (1) which comprises two superimposed pairs of frusto-conical rollers (26,27; 20,21) having their lateral surfaces tangent to the very same horizontal plane, and opposing pairs of rollers (26,21; 27,20) in the vertical plane, with their axes of rotation being symmetrically inclined, with respect to the tern of planes comprised by a first horizontal plane (h-h), or the resting plane for the lengths to be jointed, by a second vertical plane (m-m) that contains the seam-line of said lengths, and by a third vertical plane, orthogonal to both the two above-said planes.
Owing to the inclination of the axes, the pairs of the vertically opposite rollers grasp each border (E, U) of the lengths to be jointed, on both the surfaces, in correspondence of a narrow transversal portion of said fabric. Thereupon, they take said narrow transversal portion of the border, and press it against the facing border, with shifting said narrow portion progressively and with continuity, along the entire length of the seam-line.摘要翻译： 为了执行涂覆织物的两个长度（35,36）的对接接合，特别是用平行地设置在待接合边缘处的帘线加强，预期装订装置（1）包括 两个叠加的成对的截头圆锥滚子（26,27; 20,21）具有与其相同的水平面相切的侧表面，以及垂直平面中相对的一对辊（26,21; 27,20） 旋转轴相对于由第一水平面（hh）构成的平面的三角或用于要接合的长度的搁置平面对称地倾斜，第二垂直平面（mm）包含第二垂直平面 所述长度和第三垂直平面垂直于两个上述两个平面。 由于轴的倾斜度，垂直相对的辊对对应于所述织物的窄横向部分，在每个表面上抓住待接合长度的每个边界（E，U）。 于是，它们沿着边界的窄横向部分，并将其压在面对边界上，沿着缝线的整个长度逐渐地和连续地移动所述窄部分。

摘要： The invention concerns a tread-pattern of the directional type, for automobile tyres that are intended for high-powered vehicles and for exacting conditions of usage - because of the great accelerations used and the very high speeds reached during driving, even when cornering. The tread-pattern is constituted by a plurality of small blocks (5) having a substantially rhomboidal form, disposed in at least six circumferential rows and separated, one from the other, by straight circumferential grooves (1) and by oblique transversal grooves (2,3,4), with the grooves of the two assietly innermost rows, disposed astride of the mid-plane, being inclined in the contrary sense in each row - both, with respect to the next row, as well as with respect to the oblique grooves of the other remaining rows disposed in the same mid-plane as the tread-band.

摘要： A device (1) for cutting the end from a tire tread strip (3) having at least one cutting unit (4,22). When there are two cutting units (4,22) they may be positioned at a desired distance from each other and arranged for simultaneously cutting the opposite ends of a tread strip (3) arranged on a workbench (2,23). Each cutting unit (4,22) comprises a heated blade (5) which extends through a slit (11) in a transverse direction in the workbench (2,23) and moveable horizontally along the slit (11) itself in order to cut the tread strip (3) in a transverse sense. During the execution of the cut the tread strip (3) is held against the workbench (2,23) by means of a plate-like fastening element (14) which extends in a direction parallel to the slit (11) and very close to it. To the blade (5) there are connected a pressure roller (17) and a pressure sphere (18), one on each side of the cut, which operate in an elastic pushing relationship against the top of the tread strip (3) with the pressure sphere (18) moving between the tread strip (3) and the plate-like fastening element (14), to produce a pressure localized on the tread strip (3) itself in the vicinity of the cutting edge (5a) of the blade (5).

摘要： Roller table is described comprising a front supporting group (5) and a rear supporting group (8) defining respectively a front sliding surface and a rear sliding surface longitudinally aligned.
A bearing bar (11), on which lifting levers (19) are pivoted, is secured to the rear supporting group, said levers being mutually placed side by side and bearing in a rotatable manner ancillary rollers (13) at the respective upper ends. Each lifting lever is provided in the lower part with a feeler pin (17) engaged in a sliding manner along a guiding groove (16) obtained in a guiding bar (15) integral with the front supporting group. The guiding groove (16) is shaped in such a way that when the front and rear supporting groups are moved away the one from the other, the ancillary rollers (13) are lifted one by one and the one after the other and led to the level of the front and rear sliding surfaces to support a product, during its working, in the portion comprised between the spaced sliding surfaces.摘要翻译： 描述的辊台包括前支撑组（5）和后支撑组（8），后支撑组（8）分别限定纵向对准的前滑动表面和后滑动表面。 提升杆（19）枢转的支杆（11）固定到后支撑组，所述杠杆彼此并排放置，并且在相应上端以可旋转的方式支承辅助辊（13）。 每个提升杆在下部设置有沿着与在前支撑组一体的引导杆（15）中获得的引导槽（16）以滑动方式接合的触针（17）。 引导槽（16）的形状使得当前支撑组和后支撑组彼此离开时，辅助辊（13）一个接一个地升起并且一个接一个地被引导到 前部和后部滑动表面的水平面，以在其工作期间支撑产品在包括在间隔开的滑动表面之间的部分。
