Patent number: 10906334Abstract: A wrinkle detector for detecting creases or wrinkles to protect a print head of a fabric printer from occlusion by protruding fabric. The wrinkle detector comprises a mounting located in advance of a print head relative to fabric approaching to be printed, the mounting comprising one or more deflectable elements extending into a predetermined clearance zone between the printing head and the fabric, wherein deflection of the elements is used as an indicator of fabric protruding into the clearance zone. The detector may be used to halt or modify printing, in particular ink jet printing of the fabrics so that occlusion does not block the printing nozzles.Type: GrantFiled: August 2, 2017Date of Patent: February 2, 2021Assignee: Kornit Digital Ltd.Inventor: Eli Kedar

Publication number: 20200307285Abstract: Apparatus and method for digital printing comprises placing a medium to be printed on a print table and feeding towards a print head. A finite length of the medium approaching the print head is measured for variations in thickness towards the print head. Then, the height of the print head is adjusted to maintain a predetermined printing distance. Subsequently, if the extent reaches or exceeds the printing distance then it is assumed that wrinkles are present and printing is paused for readjustment of the medium, which may be a textile and more particularly a garment.Type: ApplicationFiled: June 17, 2020Publication date: October 1, 2020Applicant: Kornit Digital Ltd.Inventors: Ilan Shmuel MANO, Efraim Yohanani Naftali, Yinnon Books

Publication number: 20200262216Abstract: A printing machine for printing fabrics on a rotary drum, comprises one or more drums rotatable about a drum axis, that receive tubes of fabric thereon, and a print head placed in proximity to the drum, to print onto the fabric fitted onto the drum. The print head comprises multiple printing nozzles or linear arrays of printing nozzles which are aligned linearly along the axial direction of the drum, which are all at a predefined printing distance from the drum surface or the fabric surface. Also, a rotary drum for a textile printer comprises a groove extending along the length of the drum, and a catch mechanism built into the groove for catching on to a garment or backing for a garment as the drum rotates. The rotation of the drum pulls the caught edge and wraps the garment around the drum ready for rotary drum printing.Type: ApplicationFiled: November 7, 2018Publication date: August 20, 2020Applicant: Kornit Digital Ltd.Inventors: Nuriel AMIR, Ohad SNIR, Maor Meir AVNER
