Abstract
A device for holding sheets high in order to form gaps between sheets, during operation of a sheet pile-forming sheet-processing machine, includes vertically adjustable sheet interceptors for holding sheets high. The sheet interceptors being movable into a front pile-forming region so as to penetrate a depth therein which is so small that the sheet interceptors do not come into contact with a printed region of a sheet resting on the sheet interceptors; a sheet processing machine including the holding device; and a sheet-fed printing machine including the holding device.
Claims5
A device for holding up sheets in order to form a gap between sheets while stacking a sheet pile of the sheets in a sheet pile-forming sheet-processing machine, comprising sheet interceptors for holding up the sheets, said sheet interceptors being movable into a front pile-forming region so as to penetrate a depth therein being small enough to prevent said sheet interceptors from coming into contact with a printed region of a sheet resting on said sheet interceptors, a sensor for registering a top edge of the sheet pile and a common mounting support for said sheet interceptors and said sensor, said common mounting support being vertically adjustable.
A sheet-processing machine having a device for holding up sheets in order to form a gap between sheets while stacking a sheet pile of the sheets in the machine, comprising sheet interceptors for holding up the sheets, said sheet interceptors being movable into a front pile-forming region so as to penetrate a depth therein being small enough to prevent said sheet interceptors from coming into contact with a printed region of a sheet resting on said sheet interceptors, a sensor for registering a top edge of the sheet pile and a common mounting support for said sheet interceptors and said sensor, said common mounting support being vertically adjustable.
A sheet-fed printing machine having a device for holding up sheets in order to form a gap between sheets while stacking a sheet pile of the sheets in the machine, comprising sheet interceptors for holding up the sheets, said sheet interceptors being movable into a front pile-forming region so as to penetrate a depth therein being small enough to prevent said sheet interceptors from coming into contact with a printed region of a sheet resting on said sheet interceptors, a sensor for registering a top edge of the sheet pile and a common mounting support for said sheet interceptors and said sensor, said common mounting support being vertically adjustable.
