Abstract: 1,250,422. Warp beams of strip material; winding webs. BRUCKNER-MASCHINENBAU GERNOT BRUCKNER. 18 Feb., 1969 [11 April, 1968; 16 Dec., 1968], No. 8658/69. Heading B8R. [Also in Division Dl] A warp beam comprising a plurality of rolls of strip material 8 on a common support 7 is produced from a web 2 in a method comprising cutting the web parallel to its longitudinal direction, e.g. by a row of knives 5, and oscillating the resultant strips transversely relative to the support, e.g. by means of a reciprocating guide 6, whilst winding them on to the support. The support may be reciprocated longitudinally as well as, or instead of, the guide 6, and the amplitude of the relative oscillations is preferably between one-fifth and onehalf of the strip width. The strips may be diverged before winding, the amplitude of oscillation being less than the width of the gaps between the rolls so that the strips of adjacent rolls do not overlap. The web may be of stretched plastics film, paper, or textile material, and the resultant warp beam may be used for a weaving or knitting process. A heating tunnel 11 for relieving uneven stresses in the strips may be provided between the knives 5 and the guide 6.

The milk passes through the flow rate sensing device 25 and control valve 19 to a milk transport line 3 and the valve 17 controls the degree of vacuum applied to the teat cups from this line. The valve 17 has two chambers 8, 9 separated by flexible diaphragm 10 and connects via 6a, 14a, 15a to lines 6, 14, 15. When no milk flows, line 6 is connected to the idling vacuum line 2, as in the parent Specification 1248648 and membrane 10 is pulled by the generally high vacuum in line 3 to restrict 15a. This allows only a low, idling vacuum to be applied to the teat cups. When the milk flows line 6 is connected to higher vacuum line 1 and the diaphragm is pulled away from 15a to allow a higher vacuum to be applied to the teat cups.
